Description

Updated pidgin packages that fix three security issues are now available for Red Hat Enterprise Linux 5 and 6.

The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

Pidgin is an instant messaging program which can log in to multiple accounts on multiple instant messaging networks simultaneously.

A flaw was found in the way the Pidgin MSN protocol plug-in processed text that was not encoded in UTF-8. A remote attacker could use this flaw to crash Pidgin by sending a specially crafted MSN message. (CVE-2012-1178)

An input validation flaw was found in the way the Pidgin MSN protocol plug-in handled MSN notification messages. A malicious server or a remote attacker could use this flaw to crash Pidgin by sending a specially crafted MSN notification message. (CVE-2012-2318)

A buffer overflow flaw was found in the Pidgin MXit protocol plug-in. A remote attacker could use this flaw to crash Pidgin by sending a MXit message containing specially crafted emoticon tags. (CVE-2012-3374)

Red Hat would like to thank the Pidgin project for reporting the CVE-2012-3374 issue. Upstream acknowledges Ulf Harnhammar as the original reporter of CVE-2012-3374.

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.
