=========================================================== Ubuntu Security Notice USN-9-1 October 27, 2004 tetex-bin vulnerabilities CAN-2004-0888 =========================================================== A security issue affects the following Ubuntu releases: Ubuntu 4.10 (Warty Warthog) The following packages are affected: tetex-bin The problem can be corrected by upgrading the affected package to version 2.0.2-21ubuntu0.1. In general, a standard system upgrade is sufficient to effect the necessary changes. Details follow: 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.
