Updated pidgin packages that fix multiple security issues are now available for Red Hat Enterprise Linux 4 and 5

Solution

Before applying this update, make sure all previously-released errata relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/kb/docs/DOC-11259

Summary

Pidgin is an instant messaging program which can log in to multiple accounts on multiple instant messaging networks simultaneously.
An input sanitization flaw was found in the way the Pidgin SILC (Secure Internet Live Conferencing) protocol plug-in escaped certain UTF-8 characters. A remote attacker could use this flaw to crash Pidgin via a specially-crafted SILC message. (CVE-2011-3594)
Multiple NULL pointer dereference flaws were found in the way the Pidgin Yahoo! Messenger Protocol plug-in handled malformed YMSG packets. A remote attacker could use these flaws to crash Pidgin via a specially-crafted notification message. (CVE-2011-1091)
Red Hat would like to thank the Pidgin project for reporting CVE-2011-1091. Upstream acknowledges Marius Wachtler as the original reporter of CVE-2011-1091.
All Pidgin users should upgrade to these updated packages, which contain backported patches to resolve these issues. Pidgin must be restarted for this update to take effect.
