Red Hat: 2012:1261-01: dbus: Moderate Advisory
Summary
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.
Summary
Solution
Before applying this update, make sure all previously-released errata
relevant to your system have been applied.
