RHEL 6 : pidgin (RHSA-2011:0616)

medium Nessus Plugin ID 54598

Synopsis

The remote Red Hat host is missing one or more security updates.

Description

Updated pidgin packages that fix multiple security issues and various bugs are now available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having low security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

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

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 these issues. Upstream acknowledges Marius Wachtler as the original reporter.

This update also fixes the following bugs :

* Previous versions of the pidgin package did not properly clear certain data structures used in libpurple/cipher.c when attempting to free them. Partial information could potentially be extracted from the incorrectly cleared regions of the previously freed memory. With this update, data structures are properly cleared when freed. (BZ#684685)

* This erratum upgrades Pidgin to upstream version 2.7.9. For a list of all changes addressed in this upgrade, refer to http://developer.pidgin.im/wiki/ChangeLog (BZ#616917)

* Some incomplete translations for the kn_IN and ta_IN locales have been corrected. (BZ#633860, BZ#640170)

Users of pidgin should upgrade to these updated packages, which resolve these issues. Pidgin must be restarted for this update to take effect.

Solution

Update the affected packages.
