"An invalid pointer dereference bug was found in the way the Pidgin
OSCAR protocol implementation processed lists of contacts. A remote
attacker could send a specially crafted contact list to a user running
Pidgin, causing Pidgin to crash. (CVE-2009-3615)

A NULL pointer dereference flaw was found in the way the Pidgin IRC
protocol plug-in handles IRC topics. A malicious IRC server could send
a specially crafted IRC TOPIC message, which once received by Pidgin,
would lead to a denial of service (Pidgin crash). (CVE-2009-2703) -
SL3 only

A NULL pointer dereference flaw was found in the way the Pidgin MSN
protocol plug-in handles improper MSNSLP invitations. A remote
attacker could send a specially crafted MSNSLP invitation request,
which once accepted by a valid Pidgin user, would lead to a denial of
service (Pidgin crash). (CVE-2009-3083) - SL3 only

Pidgin must be restarted for this update to take effect."
