Adam Sampson discovered a buffer overflow in the handling of the XAUTHORITY environment variable in das-watchdog, a watchdog daemon to ensure a realtime process won't hang the machine. A local user can exploit this flaw to escalate his privileges and execute arbitrary code as root.

For the stable distribution (wheezy), this problem has been fixed in version 0.9.0-2+deb7u1.

For the unstable distribution (sid), this problem has been fixed in version 0.9.0-3.1.
