Synopsis
The remote Red Hat host is missing one or more security updates.Description
Updated pidgin packages that fix three security issues are now available for Red Hat Enterprise Linux 4 and 5.This update has been rated as having moderate security impact by the Red Hat Security Response Team.
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 'br' 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:
