Debian DLA-638-1 : policycoreutils security update

high Nessus Plugin ID 93691

Synopsis

The remote Debian host is missing a security update.

Description

It was discovered that there was a sandbox escape via the 'TIOCSTI' ioctl in policycoreutils, a set of programs required for the basic operation of an SELinux-based system.

For Debian 7 'Wheezy', this issue has been fixed in policycoreutils version 2.1.10-9+deb7u1.

We recommend that you upgrade your policycoreutils 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 policycoreutils package.
