[RHSA-2011:0320-01] Important: libcgroup security update
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Important: libcgroup security update Advisory ID: RHSA-2011:0320-01 Product: Red Hat Enterprise Linux Advisory URL: https://rhn.redhat.com/errata/RHSA-2011-0320.html Issue date: 2011-03-03 CVE Names: CVE-2011-1006 CVE-2011-1022 ===================================================================== 1. Summary: Updated libcgroup packages that fix two security issues are now available for Red Hat Enterprise Linux 6. The Red Hat Security Response Team has rated this update as having important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. 2. Relevant releases/architectures: Red Hat Enterprise Linux Desktop (v. 6) - i386, x86_64 Red Hat Enterprise Linux Desktop Optional (v. 6) - i386, x86_64 Red Hat Enterprise Linux HPC Node (v. 6) - x86_64 Red Hat Enterprise Linux HPC Node Optional (v. 6) - x86_64 Red Hat Enterprise Linux Server (v. 6) - i386, ppc64, s390x, x86_64 Red Hat Enterprise Linux Server Optional (v. 6) - i386, ppc64, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 6) - i386, x86_64 Red Hat Enterprise Linux Workstation Optional (v. 6) - i386, x86_64 3. Description: The libcgroup packages provide tools and libraries to control and monitor control groups. A heap-based buffer overflow flaw was found in the way libcgroup converted a list of user-provided controllers for a particular task into an array of strings. A local attacker could use this flaw to escalate their privileges via a specially-crafted list of controllers. (CVE-2011-1006) It was discovered that libcgroup did not properly check the origin of Netlink messages. A local attacker could use this flaw to send crafted Netlink messages to the cgrulesengd daemon, causing it to put processes into one or more existing control groups, based on the attacker's choosing, possibly allowing the particular tasks to run with more resources (memory, CPU, etc.) than originally intended. (CVE-2011-1022) Red Hat would like to thank Nelson Elhage for reporting the CVE-2011-1006 issue. All libcgroup users should upgrade to these updated packages, which contain backported patches to correct these issues. 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/kb/docs/DOC-11259 5. Bugs fixed (http://bugzilla.redhat.com/): 678107 - CVE-2011-1006 libcgroup: Heap-based buffer overflow by converting list of controllers for given task into an array of strings 680409 - CVE-2011-1022 libcgroup: Uncheck origin of NETLINK messages 6.
