Ubuntu 4.10 / 5.04 / 5.10 : xpdf, poppler, cupsys, tetex-bin vulnerabilities (USN-236-1)

critical Nessus Plugin ID 20781


The remote Ubuntu host is missing one or more security-related patches.


Chris Evans discovered several integer overflows in the XPDF code, which is present in xpdf, the Poppler library, and tetex-bin. By tricking an user into opening a specially crafted PDF file, an attacker could exploit this to execute arbitrary code with the privileges of the application that processes the document.

The CUPS printing system also uses XPDF code to convert PDF files to PostScript. By attempting to print such a crafted PDF file, a remote attacker could execute arbitrary code with the privileges of the printer server (user 'cupsys').

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.


Update the affected packages.
