Thomas Stangner discovered a vulnerability in chkrootkit, a rootkit detector, which may allow local attackers to gain root access when /tmp is mounted without the noexec option.

For the stable distribution (wheezy), this problem has been fixed in version 0.49-4.1+deb7u2. For the unstable distribution (sid), this problem has been fixed in version 0.49-5. We recommend that you upgrade your chkrootkit packages.

The chkrootkit security scanner searches the local system for signs that it is infected with a 'rootkit'. Rootkits are set of programs and hacks designed to take control of a target machine by using known security flaws.
