Summary

Pidgin is an instant messaging program which can log in to multiple accounts on multiple instant messaging networks simultaneously.
Federico Muttis of Core Security Technologies discovered a flaw in Pidgin's MSN protocol handler. If a user received a malicious MSN message, it was possible to execute arbitrary code with the permissions of the user running Pidgin. (CVE-2009-2694)
Note: Users can change their privacy settings to only allow messages from users on their buddy list to limit the impact of this flaw.
These packages upgrade Pidgin to version 2.5.9. Refer to the Pidgin release notes for a full list of changes: http://developer.pidgin.im/wiki/ChangeLog
All Pidgin users should upgrade to these updated packages, which resolve this issue. Pidgin must be restarted for this update to take effect.
