There is a remotely exploitable bug in XChat 2.0.6 that could lead to a
|
|
denial of service attack. Gentoo wishes to thank lloydbates for discovering
|
|
this bug, as well as jcdutton and rac for submitting patches to fix the bug.

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:
|
|
</p>
|
|
<code>
|
|
# emerge sync
|
|
# emerge -pv '>=net-irc/xchat-2.0.6-r1'
|
|
# emerge '>=net-irc/xchat-2.0.6-r1'
|
|
# emerge clean</code>
|
|
<p>
|
|
This assumes that users are running with ACCEPT_KEYWORDS enabled for their
|
|
architecture.
