Gentoo: 200312-06 Medium: Xchat Denial Of Service Attack

There is a remotely exploitable bug in xchat 2.0.6 that could lead to a denialof service attack. This is caused by sending a malformed DCC packet to xchat2.0.6, causing it to crash.. --------------------------------------------------------------------------- GENTOO LINUX SECURITY ANNOUNCEMENT 200312-06 --------------------------------------------------------------------------- GLSA: 200312-06 Package: net-irc/xchat Summary: Malformed dcc send requests in xchat-2.0.6 lead to a denial of service Severity: medium Gentoo bug: 35623 Date: 2003-12-14 CVE: none Exploit: remote Affected: =2.0.6 Fixed: > =2.0.6-r1 DESCRIPTION: There is a remotely exploitable bug in xchat 2.0.6 that could lead to a denial of service attack. This is caused by sending a malformed DCC packet to xchat 2.0.6, causing it to crash. Versions prior to 2.0.6 do not appear to be affected by this bug. For more information, please see: SOLUTION: For Gentoo users, xchat-2.0.6 was marked ~arch (unstable) for most architectures. Since it was never marked as stable in the portage tree, only xchat users who have explictly added the unstable keyword to ACCEPT_KEYWORDS are affected. Users may updated affected machines to the patched version of xchat using the following commands: emerge sync emerge -pv '> =net-irc/xchat-2.0.6-r1' emerge '> =net-irc/xchat-2.0.6-r1' emerge clean . A remotely exploitable bug in Xchat could lead to service disruption; upgrade to the patched version to mitigate risks.. xchat vulnerability,Gentoo denial of service,xchat update. . Severity: Medium.

Subject: [slackware-security] Security updates: at, sudo, xchat New packages are now available to address security issues with the at scheduler program (found in Slackware 8.0's bin.tgz package), sudo, and xchat. Here's the information from the Slackware 8.0 ChangeLog: Mon Jan 21 13:21:07 PST 2002 patches/packages/at.tgz: Fixed a buffer overflow. (* Security fix *) patches/packages/sudo.tgz: Upgraded to sudo-1.6.5p1. This fixes a vulnerability where the mail system could be exploited. So far, the only working examples of this problem require Postfix to be installed, but it's possible that exploits involving other mailers could emerge. (* Security fix *) patches/packages/xchat.tgz: Upgraded to xchat-1.8.7. This fixes a problem where an attacker could execute IRC server commands as the user running xchat.

Debian GNU/Linux 2.2: Remote Exploit In X-Chat URL Handling Advisory

The version of X-Chat that was distributed with Debian GNU/Linux 2.2 has a vulnerability in the URL handling code. . -----BEGIN PGP SIGNED MESSAGE------ ------------------------------------------------------------------------Debian Security Advisory This email address is being protected from spambots. You need JavaScript enabled to view it. Debian -- Security Information Wichert Akkerman August 30, 2000 - ------------------------------------------------------------------------ Package : xchat Problem type : remote exploit Debian-specific: no The version of X-Chat that was distributed with Debian GNU/Linux 2.2 has a vulnerability in the URL handling code: when a user clicks on a URL X-Chat will start netscape to view its target. However it did not check the URL for shell metacharacters, and this could be abused to trick xchat into executing arbitraty commands. This has been fixed in version 1.4.3-0.1, and we recommend you upgrade your xchat package(s) immediately. Update: the powerpc packages mentioned in the first release of this advisory were linked with a version of libgtk that is not available in Debian GNU/Linux 2.2. They have been recompiled with the correct version and reuploaded. wget url will fetch the file for you dpkg -i file.deb will install the referenced file.
