Debian DLA-847-1 : texlive-base security update

critical Nessus Plugin ID 97614

Language:

Synopsis

The remote Debian host is missing a security update.

Description

The TeX system allows for calling external programs from within the TeX source code. This has been restricted to a small set of programs since a long time ago.

Unfortunately it turned out that one program in the list, mpost, allows in turn to specify other programs to be run, which allows arbitrary code execution when compiling a TeX document.

For Debian 7 'Wheezy', these problems have been fixed in version 2012.20120611-5+deb7u1.

We recommend that you upgrade your texlive-base 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 packages.
