Debian DLA-1069-1 : tenshi security update

high Nessus Plugin ID 102789

Synopsis

The remote Debian host is missing a security update.

Description

Tenshi creates a tenshi.pid file after dropping privileges to a non-root account, which might allow local users to kill arbitrary processes by leveraging access to this non-root account for tenshi.pid modification before a root script executes a 'kill `cat /pathname/tenshi.pid`' command.

For Debian 7 'Wheezy', these problems have been fixed in version 0.13-2+deb7u1.

We recommend that you upgrade your tenshi packages.

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 tenshi package.
