It is recommended that administrators running pidgin check for an updated version of the software for their operating system. Revision History: February 19 2010: Added additional operating systems February 19 2010: Initial Release - --------------------------BEGIN INCLUDED TEXT-------------------- - -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Moderate: pidgin security update Advisory ID: RHSA-2010:0115-01 Product: Red Hat Enterprise Linux Advisory URL: https://rhn.redhat.com/errata/RHSA-2010-0115.html Issue date: 2010-02-18 CVE Names: CVE-2010-0277 CVE-2010-0420 CVE-2010-0423 ===================================================================== 1. Summary: 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. 2. Relevant releases/architectures: RHEL Desktop Workstation (v. 5 client) - i386, x86_64 RHEL Optional Productivity Applications (v. 5 server) - i386, x86_64 Red Hat Enterprise Linux AS version 4 - i386, ia64, ppc, x86_64 Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64 Red Hat Enterprise Linux Desktop version 4 - i386, x86_64 Red Hat Enterprise Linux ES version 4 - i386, ia64, x86_64 Red Hat Enterprise Linux WS version 4 - i386, ia64, x86_64 3. Description: 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: 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. 4. Solution: Before applying this update, make sure all previously-released errata relevant to your system have been applied. This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at http://kbase.redhat.com/faq/docs/DOC-11259 5. Bugs fixed (http://bugzilla.redhat.com/): 554335 - CVE-2010-0277 pidgin MSN protocol plugin memory corruption 565786 - CVE-2010-0420 pidgin: Finch XMPP MUC Crash 565792 - CVE-2010-0423 pidgin: Smiley Denial of Service 6.
