Scientific Linux Security Update : pidgin on SL4.x, SL5.x i386/x86_64

Synopsis :

The remote Scientific Linux host is missing one or more security
updates.

Description :

CVE-2009-3026 pidgin: ignores SSL/TLS requirements with old jabber
servers

CVE-2009-2703 Pidgin: NULL pointer dereference by handling IRC
topic(s) (DoS)

CVE-2009-3083 Pidgin: NULL pointer dereference by processing
incomplete MSN SLP invite (DoS)

CVE-2009-3085 Pidgin: NULL pointer dereference by processing a custom
smiley (DoS)

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)

Pidgin must be restarted for this update to take effect.
