Debian DSA-3803-1 : texlive-base - security update

critical Nessus Plugin ID 97589

Language:

Synopsis

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

Description

It was discovered that texlive-base, the TeX Live package which provides the essential TeX programs and files, whitelists mpost as an external program to be run from within the TeX source code (called \write18). Since mpost allows to specify other programs to be run, an attacker can take advantage of this flaw for arbitrary code execution when compiling a TeX document.

Solution

Upgrade the texlive-base packages.

For the stable distribution (jessie), this problem has been fixed in version 2014.20141024-2+deb8u1.

For the upcoming stable distribution (stretch), this problem has been fixed in version 2016.20161130-1.
