tag_insight = "Federico Muttis discovered that libpurple, the shared library that adds
support for various instant messaging networks to the pidgin IM client, is
vulnerable to a heap-based buffer overflow.  This issue exists because of
an incomplete fix for CVE-2008-2927 and CVE-2009-1376.  An attacker can
exploit this by sending two consecutive SLP packets to a victim via MSN.

The first packet is used to create an SLP message object with an offset of
zero, the second packet then contains a crafted offset which hits the
vulnerable code originally fixed in CVE-2008-2927 and CVE-2009-1376 and
allows an attacker to execute arbitrary code.

Note: Users with the Allow only the users below setting are not vulnerable
to this attack. If you can't install the below updates you may want to
set this via Tools->Privacy.


For the stable distribution (lenny), this problem has been fixed in
version 2.4.3-4lenny3.

For the testing distribution (squeeze), this problem will be fixed soon.

For the unstable distribution (sid), this problem has been fixed in
version 2.5.9-1.

We recommend that you upgrade your pidgin packages.";
