CVE-2011-2905

First published: Wed Aug 10 2011(Updated: )

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].
