Scientific Linux Security Update : pidgin on SL4.x, SL5.x i386/x86_64

This script is Copyright (C) 2012 Tenable Network Security, Inc.


Synopsis :

The remote Scientific Linux host is missing one or more security
updates.

Description :

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)

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.
