high Nessus Plugin ID 50643

Synopsis

The remote Red Hat host is missing a security update for pidgin.

Description

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2010:0890 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 Pidgin handled Base64 decoding. A remote attacker could use these flaws to crash Pidgin if the target Pidgin user was using the Yahoo! Messenger Protocol, MSN, MySpace, or Extensible Messaging and Presence Protocol (XMPP) protocol plug-ins, or using the Microsoft NT LAN Manager (NTLM) protocol for authentication. (CVE-2010-3711)

Red Hat would like to thank the Pidgin project for reporting these issues.
Upstream acknowledges Daniel Atallah as the original reporter.

All Pidgin users should upgrade to these updated packages, which contain a backported patch to 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 this issue 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-2010:0890.
