Pidgin is a multi-protocol Internet Messaging client.
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. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2008-2955 to this issue.
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. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2008-2957 to this issue.
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. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2008-3532 to this issue.
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.
No Avaya system products are vulnerable, as pidgin is not installed by default.
