Debian DLA-1328-1 : xerces-c security update

critical Nessus Plugin ID 108728

Synopsis

The remote Debian host is missing a security update.

Description

Alberto Garcia, Francisco Oca and Suleman Ali of Offensive Research discovered that the Xerces-C XML parser mishandles certain kinds of external DTD references, resulting in dereference of a NULL pointer while processing the path to the DTD. The bug allows for a denial of service attack in applications that allow DTD processing and do not prevent external DTD usage, and could conceivably result in remote code execution.

For Debian 7 'Wheezy', these problems have been fixed in version 3.1.1-3+deb7u5.

We recommend that you upgrade your xerces-c packages.

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

Solution

Upgrade the affected packages.
