Scientific Linux Security Update : pidgin on SL6.x i386/x86_64

Medium Nessus Plugin ID 61209


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


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 AOL Open System for Communication in Realtime (OSCAR) protocol plug-in in Pidgin, used by the AOL ICQ and AIM instant messaging systems, escaped certain UTF-8 characters. A remote attacker could use this flaw to crash Pidgin via a specially crafted OSCAR message. (CVE-2011-4601)

Multiple NULL pointer dereference flaws were found in the Jingle extension of the Extensible Messaging and Presence Protocol (XMPP) protocol plug-in in Pidgin. A remote attacker could use these flaws to crash Pidgin via a specially crafted Jingle multimedia message.

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.


Update the affected packages.
