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.
