| From the Red Hat advisory:
A NULL pointer dereference flaw was found in the way the Pidgin XMPP
protocol plug-in processes IQ error responses when trying to fetch a custom
smiley. A remote client could send a specially-crafted IQ error response
that would crash Pidgin. (CVE-2009-3085)
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)
It was discovered that, when connecting to certain, very old Jabber servers
via XMPP, Pidgin may ignore the "Require SSL/TLS" setting. In these
situations, a non-encrypted connection is established rather than the
connection failing, causing the user to believe they are using an encrypted
connection when they are not, leading to sensitive information disclosure
(session sniffing). (CVE-2009-3026)
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)
