news 28 Posted October 29, 2009 -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Moderate: pidgin security update Advisory ID: RHSA-2009:1535-01 Product: Red Hat Enterprise Linux Advisory URL: https://rhn.redhat.com/errata/RHSA-2009-1535.html Issue date: 2009-10-29 CVE Names: CVE-2009-2703 CVE-2009-3083 CVE-2009-3615 ===================================================================== 1. Summary: An updated pidgin package that fixes several security issues is now available for Red Hat Enterprise Linux 3. This update has been rated as having moderate security impact by the Red Hat Security Response Team. 2. Relevant releases/architectures: Red Hat Desktop version 3 - i386, x86_64 Red Hat Enterprise Linux AS version 3 - i386, ia64, ppc, s390, s390x, x86_64 Red Hat Enterprise Linux ES version 3 - i386, ia64, x86_64 Red Hat Enterprise Linux WS version 3 - 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 invalid pointer dereference bug was found in the way the Pidgin OSCAR protocol implementation processed lists of contacts. A remote attacker could send a specially-crafted contact list to a user running Pidgin, causing Pidgin to crash. (CVE-2009-3615) A NULL pointer dereference flaw was found in the way the Pidgin IRC protocol plug-in handles IRC topics. A malicious IRC server could send a specially-crafted IRC TOPIC message, which once received by Pidgin, would lead to a denial of service (Pidgin crash). (CVE-2009-2703) A NULL pointer dereference flaw was found in the way the Pidgin MSN protocol plug-in handles improper MSNSLP invitations. A remote attacker could send a specially-crafted MSNSLP invitation request, which once accepted by a valid Pidgin user, would lead to a denial of service (Pidgin crash). (CVE-2009-3083) All Pidgin users should upgrade to this updated package, which contains backported patches to resolve these issues. Pidgin must be restarted for this update to take effect. 4. Solution: Before applying this update, make sure that all previously-released errata relevant to your system have been applied. This update is available via 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.
