The tetex packages (teTeX) contain an implementation of TeX for Linux or UNIX systems.
A buffer overflow flaw was found in the Gfx::doImage function of Xpdf which also affects teTeX due to a shared codebase. An attacker could construct a carefully crafted PDF file that could cause teTeX to crash or possibly execute arbitrary code when opened. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-1125 to this issue.

Users should update to these erratum packages which contain backported patches to correct these issues.
