Summary
The remote host is missing an update to tex-common announced via advisory DSA 2198-1.
Insight
Insight
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. For the stable distribution (squeeze), this problem has been fixed in version 2.08.1. For the testing (wheezy) and unstable (sid) distributions, this problem will be fixed soon.
Solution
Solution
We recommend that you upgrade your tex-common packages.
