USN-2-1: xpdf vulnerabilities
Ubuntu Security Notice USN-2-1
22nd October, 2004
xpdf vulnerabilities
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 4.10
Details
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.
Update instructions
The problem can be corrected by updating your system to the following package version:
- Ubuntu 4.10:
- xpdf-utils
- xpdf-reader
- cupsys
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
