Synopsis:	Moderate: pidgin security update
Issue date:	2010-02-18
CVE Names:	CVE-2010-0277 CVE-2010-0420 CVE-2010-0423

CVE-2010-0277 pidgin MSN protocol plugin memory corruption
CVE-2010-0420 pidgin: Finch XMPP MUC Crash
CVE-2010-0423 pidgin: Smiley Denial of Service

An input sanitization flaw was found in the way Pidgin's MSN protocol
implementation handled MSNSLP invitations. A remote attacker could send 
a specially-crafted INVITE request that would cause a denial of service
(memory corruption and Pidgin crash). (CVE-2010-0277)

A denial of service flaw was found in Finch's XMPP chat implementation,
when using multi-user chat. If a Finch user in a multi-user chat session
were to change their nickname to contain the HTML "br" element, it would
cause Finch to crash. (CVE-2010-0420)

A denial of service flaw was found in the way Pidgin processed emoticon
images. A remote attacker could flood the victim with emoticon images
during mutual communication, leading to excessive CPU use. (CVE-2010-0423)

Pidgin must be restarted for this update to take effect.
