Please Install the Updated Packages.

Pidgin is an instant messaging program which can log in to multiple accounts on multiple instant messaging networks simultaneously. An input sanitization flaw was found in the way Pidgin's MSN protocol implementation handled MSNSLP invitations. A remote attacker could send a specially-crafted INVITE request that would cause a denial of service (memory corruption and Pidgin crash). (CVE-2010-0277) A denial of service flaw was found in Finch's XMPP chat implementation, when using multi-user chat. If a Finch user in a multi-user chat session were to change their nickname to contain the HTML &quot br&quot element, it would cause Finch to crash. (CVE-2010-0420) Red Hat would like to thank Sadrul Habib Chowdhury of the Pidgin project for responsibly reporting the CVE-2010-0420 issue. A denial of service flaw was found in the way Pidgin processed emoticon images. A remote attacker could flood the victim with emoticon images during mutual communication, leading to excessive CPU use. (CVE-2010-0423) These packages upgrade Pidgin to version 2.6.6. Refer to the Pidgin release notes for a full list of changes: http://developer.pidgin.im/wiki/ChangeLog All Pidgin users are advised to upgrade to these updated packages, which correct these issues. Pidgin must be restarted for this update to take effect.
