Ubuntu 4.10 : xpdf vulnerabilities (USN-14-1)

critical Nessus Plugin ID 20532

Synopsis

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

Description

Markus Meissner discovered even more integer overflow vulnerabilities in xpdf, a viewer for PDF files. These integer overflows can eventually lead to buffer overflows.

The Common UNIX Printing System (CUPS) uses the same code to print PDF files; tetex-bin uses the code to generate PDF output and process included PDF files. In any case, these vulnerabilities could be exploited by an attacker providing a specially crafted PDF file which, when processed by CUPS, xpdf, or pdflatex, 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 cases of xpdf and pdflatex, this bug could be exploited to gain the privileges of the user invoking the program.

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.

Solution

Update the affected packages.
