Debian DSA-2198-1 : tex-common - insufficient input sanitization

medium Nessus Plugin ID 52758

Synopsis

The remote Debian host is missing a security-related update.

Description

Mathias Svensson discovered that tex-common, a package shipping a number of scripts and configuration files necessary for TeX, contains insecure settings for the 'shell_escape_commands' directive. Depending on the scenario, this may result in arbitrary code execution when a victim is tricked into processing a malicious tex-file or this is done in an automated fashion.

The oldstable distribution (lenny) is not affected by this problem due to 'shell_escape' being disabled.

Solution

Upgrade the tex-common packages.

For the stable distribution (squeeze), this problem has been fixed in version 2.08.1.
