Debian DLA-194-1 : das-watchdog security update

high Nessus Plugin ID 82717

Language:

Synopsis

The remote Debian host is missing a security update.

Description

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.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected das-watchdog package.
