number of scripts and configuration files necessary for TeX, contains
insecure settings for the 'shell_escape_commands' directive. Depending

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."
