Description Josh Bressers 2009-05-12 18:08:18 EDT
The integer overflow fix for CVE-2008-2927 was incomplete on 32 bit
platforms. If a Pidgin user can receive a specially crafted MSN message,
it may be possible to execute arbitrary code with the permissions of the
user running Pidgin.

This flaw is only exploitable by individuals who can message a user, which
is controlled by the Pidgin privacy setting.  The default setting is to
only allow messages from users in the buddy list.
