Description Vincent Danen 2011-08-10 21:43:21 UTC
It was reported [1] that perf would look for configuration files in /etc/perfconfig, ~/.perfconfig, and ./config.  If ./config is not a perf configuration file, perf could fail or possibly do unexpected things.  If a privileged user was tricked into running perf in a directory containing a malicious ./config file, it could possibly lead to the execution of arbitrary commands.

A patch is available [2].

Comment 1 Vincent Danen 2011-08-10 21:47:38 UTC
Created kernel tracking bugs for this issue

Affects: fedora-all [bug 729809]

Comment 5 Eugene Teo (Security Response) 2011-08-12 07:05:06 UTC

This issue did not affect Red Hat Enterprise Linux 4 and 5 as they did not include support for perf. This did not affect Red Hat Enterprise MRG as it uses the perf package from Red Hat Enterprise Linux 6. This has been addressed in Red Hat Enterprise Linux 6 via https://rhn.redhat.com/errata/RHSA-2011-1465.html.
