  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. (CVE-2011-4602)

  Red Hat would like to thank the Pidgin project for reporting these issues.
  Upstream acknowledges Evgeny Boger as the original reporter of
  CVE-2011-4601, and Thijs Alkemade as the original reporter of
  CVE-2011-4602.

  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.");
