Synopsis:	Moderate: pidgin security update
Issue date:	2010-10-21
CVE Names:	CVE-2010-1624 CVE-2010-3711

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)

A NULL pointer dereference flaw was found in the way the Pidgin MSN
protocol plug-in processed custom emoticon messages. A remote attacker
could use this flaw to crash Pidgin by sending specially-crafted
emoticon messages during mutual communication. (CVE-2010-1624)

Pidgin must be restarted for this update to take effect.
