Read the bulletin. There's no patch. It is deemed by Microsoft to be of low impact and thus no patch has been built.

Microsoft Security Bulletin MS09-048 - Critical: Vulnerabilities in Windows TCP/IP Could Allow Remote Code Execution (967723): http://www.microsoft.com/technet/security/Bulletin/MS09-048.mspx If Windows XP is listed as an affected product, why is Microsoft not issuing an update for it?By default, Windows XP Service Pack 2, Windows XP Service Pack 3, and Windows XP Professional x64 Edition Service Pack 2 do not have a listening service configured in the client firewall and are therefore not affected by this vulnerability. Windows XP Service Pack 2 and later operating systems include a stateful host firewall that provides protection for computers against incoming traffic from the Internet or from neighboring network devices on a private network. The impact of a denial of service attack is that a system would become unresponsive due to memory consumption. However, a successful attack requires a sustained flood of specially crafted TCP packets, and the system will recover once the flood ceases. This makes the severity rating Low for Windows XP. Windows XP is not affected by CVE-2009-1925. Customers running Windows XP are at reduced risk, and Microsoft recommends they use the firewall included with the operating system, or a network firewall, to block access to the affected ports and limit the attack surface from untrusted networks.

Re: 3rd party patch for XP for MS09-048?
Reference: http://www.computerworld.com/s/article/9138007/Microsoft_No_TCP_IP_patches_for_you_XP MS claims the patch would require to much overhaul of XP to make it worth it, and they may be right. Who knows how many applications might break that were designed for XP if they have to radically change the TCP/IP stack. Now, I don't know if the MS speak is true, but it certainly sounds like it is not going to be patched. The other side of the MS claim is that a properly-firewalled XP system would not be vulnerable to a DOS anyway, so a patch shouldn't be necessary. -Eric Original Message Subject: Re: 3rd party patch for XP for MS09-048?

Re: Improper Authentication Mechanism in 3Com Wireless8760 Dual Radio 11a/b/g Poe Access Point
Hi Yossi, Are you doing something funky with your IP address, e.g., NAT'ed/short DHCP lease? The reason I ask is because in 2008, Adrian Pastor stated authentication in the 3Com Wireless 8760 was linked to the source IP address [1]. It may well be the case (as you have discovered) that it allows arbitrary IP addresses to access the config once an administrator has authentication... However, I just wanted to hit this badboy up incase there was some confusion.

It's not that they aren't supported per se, just that Microsoft has deemed the impact of DOS to be low, the ability to patch that platform impossible/difficult and thus have make a risk calculation accordingly.

The quote that stands out most for me: During the Q&A, however, Windows users repeatedly asked Microsoft's security team to explain why it wasn't patching XP, or if, in certain scenarios, their machines might be at risk. "We still use Windows XP and we do not use Windows Firewall," read one of the user questions. "We use a third-party vendor firewall product. Even assuming that we use the Windows Firewall, if there are services listening, such as remote desktop, wouldn't then Windows XP be vulnerable to this?" "Servers are a more likely target for this attack, and your firewall should provide additional protections against external exploits," replied Stone and Bryant. If an employee managing a product that my company owned gave answers like that to a public interview with Computerworld, they would be in deep doo. First off, my default install of XP Pro SP2 has remote assistance inbound, and once you join to a domain, you obviously accept necessary domain traffic. This "no inbound traffic by default so you are not vulnerable" line is crap. It was a direct question - "If RDP is allowed through the firewall, are we vulnerable?" A:"Great question. Yes, servers are the target. A firewall should provide added protection, maybe. Rumor is that's what they are for. Not sure really. What was the question again?" You don't get "trustworthy" by not answering people's questions, particularly when they are good, obvious questions. Just be honest about it. "Yes, XP is vulnerable to a DOS. Your firewall might help, but don't bet on it. XP code is something like 15 years old now, and we're not going to change it. That's the way it is, sorry. Just be glad you're using XP and not 2008/vista or you'd be patching your arse off right now." If MSFT thinks they are mitigating public opinion issues by side-stepping questions and not fully exposing the problems, they are wrong. This just makes it worse. That's the long answer.

RE: [Full-disclosure] 3rd party patch for XP for MS09-048?
I agree that the FAQ explanation in the advisory is vague about what protection the firewall provides. One clue I would infer about it is that they rated this a "Low" threat. If it were vulnerable in the default configuration, with the firewall (or some other firewall) on, they probably would have rated it at least Medium. If I'm wrong about that then the "Low" rating is misleading.

P.S. Anyone check to see if the default "XP Mode" VM you get for free with Win7 hyperv is vulnerable and what the implications are for a host running an XP vm that get's DoS'd are? I get the whole "XP code to too old to care" bit, but it seems odd to take that "old code" and re-market it around compatibility and re-distribute it with free downloads for Win7 while saying "we won't patch old code." t > -Original Message- > From: full-disclosure-boun...@lists.grok.org.uk [mailto:full- > disclosure-boun...@lists.grok.org.uk] On Behalf Of Thor (Hammer of God) > Sent: Wednesday, September 16, 2009 8:00 AM > To: Eric C.

Exploiting Chrome and Opera's inbuilt ATOM/RSS reader with Script Execution and more
Exploiting Chrome and Operas inbuilt ATOM/RSS reader with Script Execution and more - For complete post (with images), please visit - http://securethoughts.com/2009/09/exploiting-chrome-and-operas-inbuilt-atomr ss-reader-with-script-execution-and-more/ = SECURETHOUGHTS.COM ADVISORY - CVE-ID: CVE-2009- (Chrome) {Pending} - Release Date : September 15, 2009 - Severity : Medium to High - Discovered by : Inferno = I. TITLE - Exploiting Chrome and Operas inbuilt ATOM/RSS reader with Script Execution and more II. VULNERABLE - Chrome all versions 2 and 3 (< 3.0.195.21) Opera all versions - 9 and 10. III. BACKGROUND - Back in 2006, there was interesting research done by James Holderness[1] and James M. Snell[2] which uncovered a variety of XSS issues in various online feed aggregator services (e.g. Feed Demon). The vulnerability arises from the fact that it is not expected of RSS readers to render scripted content. I want to extend that research by doing threat analysis on inbuilt feed readers offered in most modern browsers. I have found Google Chrome (v2,3) and Opera (v9,v10) to be vulnerable, while Internet Explorer(v7,8), Firefox 3.5 and Safari 4 are resilient to the exploits mentioned below. IV. DESCRIPTION - Google Chrome and Operas inbuilt RSS/ATOM Reader renders untrusted javascript in an RSS/ATOM feed. Exploit Scenarios 1. Scenario 1 1. Attacker social engineers a victim user to visit a rss/atom feed link pointing to his or her evil site. 2. Victim uses Google Chrome / Opera browser to view the feed. 3. Malicious javascript gets executed on victims browser. Examples 1. Modifies into a phishing page and asks user credentials for subscribing to Google Reader / My.Opera.com 2. Searches users browser history for visited url list [3] 3. Scans users internal network with/without javascript [4] 2. Scenario 2 1. Both attacker and victim user have an account to a trusted website. 2. Either 1. The trusted web site lets the attacker inject JavaScript content into any section of the sites RSS or an Atom feed. 3. OR 1. The trusted website uses blacklist to block known executable file types for scripted content. E.g. html, jsp, etc. 2. Attacker uploads a file with extension .rss/.atom/arbitary extension preceded by .rss/.atom [e.g. .atom.tx]. Most widely used Apache web server passes Content-Type as application/{atom/rss}+xml for all the three cases automatically in default configuration. 3. Attacker convinces victim to visit the direct link to uploaded file. 4. Victims cookies and other sensitive data gets sent to attackers site. 5. Note: For Internet Explorer (v7,8), the task is easier because it does automatic mime type detection. So, you can execute javascript content in any file extension. E.g. click http://securethoughts.com/security/rssatomxss/anyfile.tx. However, for other browsers, Firefox 3.5, Safari 4, Opera 10 and Chrome 3, they dont support this functionality (perhaps for security reasons). So, using such extensions mentioned above can be used as a workaround for script execution in Opera and Chrome browsers. 3. Scenario 3 1. Similar to Scenario 1, but exploit can be used for complete control over feeds in the Opera browser. V. PROOF OF CONCEPT - 1. Exploit Scenario 1 [Testcases - 18 XSS for Chrome, 38 XSS for Opera] 1. Chrome: http://securethoughts.com/security/rssatomxss/googlechromexss.atom [or .rss] 2. Opera: http://securethoughts.com/security/rssatomxss/opera10xss.atom [or .rss] 2. Exploit Scenario 2 1. Include all in Scenario 1 2. Opera: http://securethoughts.com/security/rssatomxss/opera10xss.atom.tx [Any arbitary file extension at. E.g .tx, .tm] 3. Chrome: http://securethoughts.com/security/rssatomxss/googlechromexss.atom.tx [Any arbitary file extension at. E.g .tx, .tm] 3. Exploit Scenario 3 1. Details and PoC will be released after patch is provided by Opera Security Team in next minor release. For research purposes, you can try out the PoCs on these virtualized (and vulnerable) versions of various browsers, without installing any bits on your computer [5]. VI. FIX DESCRIPTION - Chrome: ATOM/RSS feed rendering is completely disabled by forcing a text/plain MIME type [6]. If you need feed rendering, a good alternative is FeedBurner which protects from any script execution attacks by blocking them at time of the feed registration. Opera: Scenarios (1) and (2)
Re: 3rd party patch for XP for MS09-048?
Is this relevant? QUOTE--- Protect to 2 for the best protection against SYN attacks. This value adds additional delays to connection indications, and TCP connection requests quickly timeout when a SYN attack is in progress. This parameter is the recommended setting. NOTE: The following socket options no longer work on any socket when you set the SynAttackProtect value to 2: Scalable windows - IIRC? This is called the "Silly Window Syndrome", & this is a way, in theory, around it... & iirc, "Scalable Windows", via setsockopt API calls from an attacker are what the problem is here anyhow & this ought to 'stall it'... thoughts/feedback? APK P.S.=> Also, "hardcoding" the TcpWindowSize & GlobalTcpWindowSize settings in the registry in TCP/IP Parameters (see registry path above) SHOULD also help here also, for servers that can accept MANY connections from MANY clients, worldwide, as your specific constraints specify... Thus, effectively stalling the ability to use TcpWindowScaling is stopped by SynAttackProtect too, so an attacking system/app sending a setsockopt of 0 for this SHOULD also be nullified, on a server also... (However/Again - Workstations are easily taken care of , vs. servers, just by what I wrote up above either by PORT FILTERING) IP Security Policies, which can work on ranges of addresses to block, OR, single systems as well you either ALLOW or DENY to talk to your system, still can help also... vs. a DDOS though? SynAttackProtect is your best friend here... you'd use netstat -b -n tcp to see which are held in a 1/2 open SYN-RECEIVE state, & BLOCK THOSE FROM SENDING YOUR WAY (or just by doing it in a router or routing table)... takers anyone, on these thoughts (especially for Windows 2000)?

RE: [Full-disclosure] 3rd party patch for XP for MS09-048?
Hey Larry- hope everything's going well... When you've got a systemic vulnerability, in this case the TCP/IP stack itself, exploitation information must be explicit and definitive. I'm fine with risk classification, and I appreciate efforts to categorize risk into manageable exposure metrics, but we shouldn't have to infer potential vulnerability information from vague disclosure data. I know many response teams base patch paths on the published severity, but one also has to be able to make decisions on their own. For me, no big deal. But it's not that simple for others. But there's not enough information for me to make that call. Is it for ANY "listening service?" TCP or UPD? Does the "statefull" firewall introduced in subsequent versions stop it? The answers are "yes," "yes," and "no." They should just say that. Is it "low" because the firewall doesn't have any exceptions by default? If so, that's silly. Everyone using XP for anything has incoming connections for something, and well known if on a domain. I feel sorry for Diebold and NEC with all the ATMs out there running XP, but fortunately, I'm not responsible for clients using their systems anymore :) Anyway, the DoS suxx0rz, but I'm more irritated with the lack of real, straight-forward, no-nonsense information and technical sleight of hand.

Iret #GP on pre-commit handling failure: the NetBSD case (CVE-2009-2793)
Iret #GP on pre-commit handling failure: the NetBSD case (CVE-2009-2793) On the Intel architecture, once an operating system kernel has completed servicing an interrupt or exception, it will generally return to user mode using iret. The iret instruction will restore the context required to continue execution, such as code segment, instruction pointer, flags and so on. iret is a complex instruction whose pseudocode alone spans several pages of the software developers manual. Interestingly, in protected mode it is executed in two distinct stages, a pre-commit stage (before privilege level is changed) and a post-commit stage (after privilege level is changed). You can see the commit point in the pseudocode below (taken from Intel manual, comment is ours) IF new mode != 64-Bit Mode THEN IF tempEIP is not within code segment limits THEN #GP(0); FI; EIP <- tempEIP; ELSE (* new mode = 64-bit mode *) IF tempRIP is non-canonical THEN #GP(0); FI; RIP <- tempRIP; FI; CS <- tempCS; // This is the commit point (privilege switch) EFLAGS (CF, PF, AF, ZF, SF, TF, DF, OF, NT) <- tempEFLAGS; When the processor handles an exception, two cases can arise: - the handler procedure is executed at the same level of privilege as the interrupted procedure, no stack switch occurs - the handler procedure is executed at a different privilege level, therefore a stack switch occurs The generated stack frame will be different if a stack switch occurs, because the processor needs to save the interrupted procedure's stack. When iret returns to a different privilege level, its behaviour on failure will depend on which stage of the operation it is currently executing. A pre-commit failure will induce no stack-switching while a post-commit failure will induce a stack switching and therefore generate a different size trap frame. Affected Software It's easy to overlook this distinction and we have found multiple cases where this has had direct security consequences or made other issues exploitable. For instance, the NetBSD kernel on x86 does not handle pre-commit failures properly. We can easily make iret fail pre-commit by having tempEIP outside the code segment limits. - The canonical way to do this is to set-up a LDT entry with a code segment limited to 0x1FFF. mmap memory at 0x1000 and then put some shellcode with an int 0x80 at the very end of this page, so that when the kernel iret, tempEIP is past the code segment limits. - Interestingly, because of the lazy handling of non executable stack emulation on x86, this bug could be triggered by a non malicious program: /* ... */ int main(int argc, char **argv) { jmp_buf env; void handlesig(int n) { longjmp(env, 1); } signal(SIGSEGV, handlesig); if (setjmp(env) == 0) { ( (void(*)(void)) NULL) (); } return 0; } /* ... */ int main(int argc, char **argv) { char baguette; signal(SIGABRT, (void (*)(int))&baguette); abort(); } Consequences --- In the NetBSD case, the kernel stack will get desynchronized. This might allow an attacker to elevate privileges. --- Solution --- We reported this to NetBSD developpers in May. Obviously, the fix is non trivial, and after much discussion, we agreed to release this information to open this issue to the wider NetBSD developement community. --- Credit --- This bug was discovered by Tavis Ormandy and Julien Tinnes of the Google Security Team.

Re: 3rd party patch for XP for MS09-048?
Cloud option maybe as we go forward but right now today, this is business making the decisions here. Desktop, if it were that easy we'd have ripped out desktops years ago. Businesses have to be realistic. Sometimes there is not "plenty of comparable alternatives out there". Sometimes the boss/business needs/line of business apps dictates you run windows.

RE: [Full-disclosure] 3rd party patch for XP for MS09-048?
Yes, they used the bulletin to soft-pedal the description, but at the same time I think they send a message about XP users being on shaky ground. Just because they've got 4+ years of Extended Support Period left doesn't mean they're going to get first-class treatment.

It's only "default" for people running XP standalone/consumer that are not even in a home network settings. That kinda slices and dices that default down to a VERY narrow sub sub sub set of customer base.

Say "THERE WILL BE NO PATCH, EVER. HERE'S EVERYTHING WE KNOW SO YOU CAN DETERMINE YOUR OWN RISK." Also, don't say 'you can deploy firewall settings via group policy to mitigate exposure' when the firewall obviously must be accepting network connections to get the settings in the first place.

If you are going to try to boot sales of Win7 to corporate customers by providing free XP VM technology and thus play up how important XP is and how many companies still depend upon it for business critical application compatibility, don't deploy that technology in an other-than-default configuration that is subject to a DoS exploit while downplaying the extent that the exploit may be leveraged by saying that a "typical" default configuration mitigates it while choosing not to ever patch it.Seems like simple logic points to me. > > t > > >> -Original Message- >> From: Susan Bradley [mailto:sbrad...@pacbell.net] >> Sent: Wednesday, September 16, 2009 10:16 AM >> To: Thor (Hammer of God) >> Cc: bugtraq@securityfocus.com; full-disclos...@lists.grok.org.uk >> Subject: Re: [Full-disclosure] 3rd party patch for XP for MS09-048? >> >> It's XP.

"We still use Windows XP and we do not use Windows Firewall," read one of the user questions. "We use a third-party vendor firewall product.
