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.
