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.
