New tetex packages are available for Slackware 10.2 and -current to fix a possible security issue. teTeX-3.0 incorporates some code from the xpdf program which has been shown to have various overflows that could result in program crashes or possibly the execution of arbitrary code as the teTeX user. This is especially important to consider if teTeX is being used as part of a printer filter.
