RE: [SECURITY] [DSA 1720-1] New TYPO3 packages fix several vulnerabilities
Copy this link into the address bar of explorer. Should take you to the installer.

Marcus Krause and Michael Stucki from the TYPO3 security team discovered that the jumpUrl mechanism discloses secret hashes enabling a remote attacker to bypass access control by submitting the correct value as a URL parameter and thus being able to read the content of arbitrary files. Jelmer de Hen and Dmitry Dulepov discovered multiple cross-site scripting vulnerabilities in the backend user interface allowing remote attackers to inject arbitrary web script or HTML. As it is very likely that your encryption key has been exposed we strongly recommend to change your encyption key via the install tool after installing the update. For the stable distribution (etch) these problems have been fixed in version 4.0.2+debian-8. For the testing distribution (lenny) these problems have been fixed in version 4.2.5-1+lenny1. For the unstable distribution (sid) these problems have been fixed in version 4.2.6-1. We recommend that you upgrade your typo3 package. Upgrade Instructions - wget url will fetch the file for you dpkg -i file.deb will install the referenced file. If you are using the apt-get package manager, use the line for sources.list as given at the end of this advisory: apt-get update will update the internal database apt-get upgrade will install corrected packages You may use an automated update by adding the resources from the footer to the proper configuration.

E.g. I have eth0 which is connected to the insecure network, and my encrypted tunnel to a secure network. Although the tunnel is available, the unsecure eth0 is still also available. I need to correctly set up the SOCKS proxy or set up the routing tables, or do something to be sure that all my network traffic is going through the tunnel and not just directly to the unsecure eth0. There's no easy way to tell if you're doing it right, either, since the web looks basically the same from the unsecure network as from the secure one. The Cisco VPN I use on my employer's Windows machine has an interesting feature: it completely hides the unencrypted network. Once I create the VPN tunnel, my machine releases it's local IP address and there is no way for any network connections (other than the tunnel, of course) to go over the unencrypted device. It is as if that device is disabled. This makes it idiotproof, which is an important but often overlooked aspect of security. So, is is possible to do that sort of thing with a Linux laptop? --- Wade -- ___ . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . / \ Plain text e-mail | Wade Richards --- w...@wabyn.net | RIP |c1970 ~ c2000| You can never tell which way the train went |ASCII| Killed by HTML/RTF | by looking at the tracks. | | in e-mail | -- To UNSUBSCRIBE, email to debian-security-requ...@lists.debian.org with a subject of "unsubscribe".

The devices may be specified by numerical ID or the keyword “any”, which uses the next available tunnel device. If remote_tun is not specified, it defaults to “any”. See also the Tunnel and TunnelDevice directives in ssh_config(5). If the Tunnel directive is unset, it is set to the default tunnel mode, which is “point-to-point”. /yosh (sorry for the lack of precision, I r tired) -- To UNSUBSCRIBE, email to debian-security-requ...@lists.debian.org with a subject of "unsubscribe".
