USN-2-1: xpdf vulnerabilities
First published: Sat Oct 23 2004(Updated: )
Chris Evans discovered several integer overflow vulnerabilities in xpdf, a viewer for PDF files. The Common UNIX Printing System (CUPS) also uses the same code to print PDF files. In either case, these vulnerabilities could be exploited by an attacker by providing a specially crafted PDF file which, when processed by CUPS or xpdf, could result in abnormal program termination or the execution of program code supplied by the attacker. In the case of CUPS, this bug could be exploited to gain the privileges of the CUPS print server (by default, user cupsys). In the case of xpdf, this bug could be exploited to gain the privileges of the user invoking xpdf.
