Detail
Problem Description: Updated vino packages that fix one security issue are now available for Red Hat Enterprise Linux 5 and 6. The Red Hat Security Response Team has rated this update as having moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section. 2. Relevant releases/architectures: Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64 Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64 Red Hat Enterprise Linux Desktop (v. 6) - i386, x86_64 Red Hat Enterprise Linux Server (v. 6) - i386, ppc64, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 6) - i386, x86_64 3. Description: Vino is a Virtual Network Computing (VNC) server for GNOME. It allows remote users to connect to a running GNOME session using VNC. A denial of service flaw was found in the way Vino handled certain authenticated requests from clients that were in the deferred state. A remote attacker could use this flaw to make the vino-server process enter an infinite loop when processing those incoming requests. (CVE-2013-5745) All vino users are advised to upgrade to these updated packages, which contain a backported patch to correct this issue. The GNOME session must be restarted (log out, then log back in) 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 https://access.redhat.com/site/articles/11258 5.
