USN-9-1: tetex-bin vulnerabilities

28 October 2004

tetex-bin vulnerabilities



Chris Evans and Marcus Meissner recently discovered several integer
overflow vulnerabilities in xpdf, a viewer for PDF files. Because
tetex-bin contains xpdf code, it is also affected. These
vulnerabilities could be exploited by an attacker providing a
specially crafted TeX, LaTeX, or PDF file. Processing such a file with
pdflatex could result in abnormal program termination or the execution
of program code supplied by the attacker.

This bug could be exploited to gain the privileges of the user
invoking pdflatex.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 4.10
  • tetex-bin -

In general, a standard system update will make all the necessary changes.
