Description

Pidgin is a multi-protocol Internet Messaging client.A denial-of-service flaw was found in Pidgin's MSN protocol handler. If aremote user was able to send, and the Pidgin user accepted, acarefully-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 toPidgin, causing it to download an excessive amount of data, consuming allavailable memory or disk space. (CVE-2008-2957)A flaw was found in the way Pidgin handled SSL certificates. The NSS SSLimplementation in Pidgin did not properly verify the authenticity of SSLcertificates. This could have resulted in users unknowingly connecting to amalicious SSL service. (CVE-2008-3532)In addition, this update upgrades pidgin from version 2.3.1 to version2.5.2, with many additional stability and functionality fixes from thePidgin Project.Note: the Secure Internet Live Conferencing (SILC) chat network protocolhas recently changed, affecting all versions of pidgin shipped with Red HatEnterprise 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. Thisupdate does not correct this. Red Hat Bugzilla #474212 (linked to in theReferences section) has more information.Note: after the errata packages are installed, Pidgin must be restarted forthe update to take effect.All Pidgin users should upgrade to these updated packages, which containsPidgin version 2.5.2 and resolves these issues.
