CVE-2011-2905

Publication date 6 October 2011

Last updated 24 July 2024

Ubuntu priority

Medium

Why this priority?

Untrusted search path vulnerability in the perf_config function in tools/perf/util/config.c in perf, as distributed in the Linux kernel before 3.1, allows local users to overwrite arbitrary files via a crafted config file in the current working directory.

From the Ubuntu Security Team

Christian Ohm discovered that the perf command looks for configuration files in the current directory. If a privileged user were tricked into running perf in a directory containing a malicious configuration file, an attacker could run arbitrary commands and possibly gain privileges.
