Debian DSA-3610-1 : xerces-c - security update

high Nessus Plugin ID 91892

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

Brandon Perry discovered that xerces-c, a validating XML parser library for C++, fails to successfully parse a DTD that is deeply nested, causing a stack overflow. A remote unauthenticated attacker can take advantage of this flaw to cause a denial of service against applications using the xerces-c library.

Additionally this update includes an enhancement to enable applications to fully disable DTD processing through the use of an environment variable (XERCES_DISABLE_DTD).

Solution

Upgrade the xerces-c packages.

For the stable distribution (jessie), this problem has been fixed in version 3.1.1-5.1+deb8u3.
