===================================================================== Red Hat Security Advisory
Synopsis: Moderate: dbus security update Advisory ID: RHSA-2012:1261-01 Product: Red Hat Enterprise Linux Advisory URL: https://rhn.redhat.com/errata/RHSA-2012-1261.html Issue date: 2012-09-13 CVE Names: CVE-2012-3524 =====================================================================
1. Summary:
Updated dbus packages that fix one security issue are now available for Red Hat Enterprise Linux 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 Desktop (v. 6) - i386, x86_64 Red Hat Enterprise Linux Desktop Optional (v. 6) - i386, noarch, x86_64 Red Hat Enterprise Linux HPC Node (v. 6) - x86_64 Red Hat Enterprise Linux HPC Node Optional (v. 6) - noarch, x86_64 Red Hat Enterprise Linux Server (v. 6) - i386, ppc64, s390x, x86_64 Red Hat Enterprise Linux Server Optional (v. 6) - noarch Red Hat Enterprise Linux Workstation (v. 6) - i386, x86_64 Red Hat Enterprise Linux Workstation Optional (v. 6) - noarch
3. Description:
D-Bus is a system for sending messages between applications. It is used for the system-wide message bus service and as a per-user-login-session messaging facility.
It was discovered that the D-Bus library honored environment settings even when running with elevated privileges. A local attacker could possibly use this flaw to escalate their privileges, by setting specific environment variables before running a setuid or setgid application linked against the D-Bus library (libdbus). (CVE-2012-3524)
Note: With this update, libdbus ignores environment variables when used by setuid or setgid applications. The environment is not ignored when an application gains privileges via file system capabilities; however, no application shipped in Red Hat Enterprise Linux 6 gains privileges via file system capabilities.
Red Hat would like to thank Sebastian Krahmer of the SUSE Security Team for reporting this issue.
All users are advised to upgrade to these updated packages, which contain a backported patch to correct this issue. For the update to take effect, all running instances of dbus-daemon and all running applications using the libdbus library must be restarted, or the system rebooted.
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/knowledge/articles/11258
5. Bugs fixed (http://bugzilla.redhat.com/):
847402 - CVE-2012-3524 X.org: arbitrary code execution as root when libdbus >= 1.5 is used
