finch, libpurple, pidgin security update

CentOS Errata and Security Advisory CESA-2009:1218

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.
