Synopsis:	Moderate: pidgin security and bug fix update
Issue date:	2008-12-15
CVE Names:	CVE-2008-2955 CVE-2008-2957 CVE-2008-3532

A denial-of-service flaw was found in Pidgin's MSN protocol handler. If a
remote user was able to send, and the Pidgin user accepted, a
carefully-crafted file request, it could result in Pidgin crashing.
(CVE-2008-2955)

A denial-of-service flaw was found in Pidgin's Universal Plug and Play
(UPnP) request handling. A malicious UPnP server could send a request to
Pidgin, causing it to download an excessive amount of data, consuming all
available memory or disk space. (CVE-2008-2957)

A flaw was found in the way Pidgin handled SSL certificates. The NSS SSL
implementation in Pidgin did not properly verify the authenticity of SSL
certificates. This could have resulted in users unknowingly connecting to a
malicious SSL service. (CVE-2008-3532)

In addition, this update upgrades pidgin from version 2.3.1 to version
2.5.2, with many additional stability and functionality fixes from the
Pidgin Project.

Note: the Secure Internet Live Conferencing (SILC) chat network protocol
has recently changed, affecting all versions of pidgin shipped with Red Hat
Enterprise Linux.

Pidgin cannot currently connect to the latest version of the SILC server
(1.1.14): it fails to properly exchange keys during initial login. This
update does not correct this. Red Hat Bugzilla #474212 (linked to in the
References section) has more information.

Note: after the errata packages are installed, Pidgin must be restarted for
the update to take effect.
