USN-9-1: tetex-bin vulnerabilities

28 October 2004

tetex-bin vulnerabilities

A security issue affects these releases of Ubuntu and its derivatives:

  • Ubuntu 4.10

Software Description

Details

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
