RHEL 6 : pidgin (RHSA-2011:0616)

medium Nessus Plugin ID 54598

Synopsis

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

Description

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2011:0616 advisory.

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.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL pidgin package based on the guidance in RHSA-2011:0616.
