Security researcher acknowledgement Hello, I'm writing to let you know that the security researcher acknowledgement for the issue we recently reported to you is now up at http://technet.microsoft.com/en-US/dn613815 Thank you again for tending to our report in a timely manner. Mollie MSVR -Original Message- From: boun...@canonical.com [mailto:boun...@canonical.com] On Behalf Of Seth Arnold Sent: Friday, May 9, 2014 3:25 PM To: Microsoft Vulnerability Research Subject: [Bug 1313194] Re: Bochs Multiple Vulnerabilities Mollie, please feel free to publish, however I still believe that someone who does not inspect a .bxrc before using it is running larger risks due to the intentional features of the file format rather than the unintentional bugs found and disclosed here. The similar report on OSVDB for VMWare Player expresses a similar sentiment: EMC VMware Player contains a flaw that may allow a local denial of service. The issue is triggered when a user loads a .vmx file containing an ide1:0.fileName parameter with an overly long value, and will result in loss of availability for the the VMware instace. However, for an attacker to gain access and edit the .vmx file, it would require a level of access that would allow a wide variety of attacks. This level of access is considered to be trusted and not readily available to someone looking to launch this type of attack. >From http://osvdb.com/show/osvdb/27524.

RE: [Bug 1313194] Re: Bochs Multiple Vulnerabilities
Hello there! Thanks much for taking a look at this, very much appreciated. More info attached. No CVE as yet, though I'd love to get one. Have been attempting to contact Bochs for months. Mollie -Original Message- From: boun...@canonical.com [mailto:boun...@canonical.com] On Behalf Of Seth Arnold Sent: Monday, April 28, 2014 11:04 PM To: Microsoft Vulnerability Research Subject: [Bug 1313194] Re: Bochs Multiple Vulnerabilities Mollie, thanks for forwarding this report; do you know if the issue is strictly a matter of properly constructed image file or is this something that could be influenced from "inside" the system being emulated? Do you know if the example PoC files are available? Do you know if this has been reported to upstream Bochs developers? Do you know if any CVE numbers have been assigned? Thanks ** Information type changed from Private Security to Public Security -- You received this bug notification because you are subscribed to the bug report. https://bugs.launchpad.net/bugs/1313194 Title: Bochs Multiple Vulnerabilities Status in “bochs” package in Ubuntu: New Bug description: MSVR Vulnerability Report Discovered by: Jeremy Brown (jerbrown) of ReSP Date: 06-17-2013 Title: Bochs Multiple Vulnerabilities Product: Bochs PC Emulator Version: 2.6.2 (latest) URL: http://bochs.sourceforge.net Download Link: http://sourceforge.net/projects/bochs/files/bochs/2.6.2/ Repro File(s): repro1.bxrc, repro2.bxrc Product Description Bochs is a highly portable open source IA-32 (x86) PC emulator written in C++, that runs on most popular platforms. It includes emulation of the Intel x86 CPU, common I/O devices, and a custom BIOS. Bochs can be compiled to emulate many different x86 CPUs, from early 386 to the most recent x86-64 Intel and AMD processors which may even not reached the market yet. Vulnerability Description Two vulnerabilities were found in Bochs’s parsing of bxrc files (configuration), a format string vulnerability and a stack corruption vulnerability. Both of these could potentially allow an attacker to execute arbitrary code in the context of the user running Bochs. Technical Details I tested Bochs by running boches.exe -q -f [bxrc-file]. The first one is a format string vulnerability (repro1.bxrc) when boches parses the “floppya” field: The second vulnerability (repro2.bxrc) occurs boches parses the “romimage” field. See debugging output below for more info.
