Debian DSA-4814-1 : xerces-c - security update

high Nessus Plugin ID 144437

Language:

Synopsis

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

Description

It was discovered that xerces-c, a validating XML parser library for C++, did not correctly scan DTDs. The use-after-free vulnerability resulting from this issue would allow a remote attacker to leverage a specially crafted XML file in order to crash the application or potentially execute arbitrary code. Please note that the patch fixing this issue comes at the expense of a newly introduced memory leak.

Solution

Upgrade the xerces-c packages.

For the stable distribution (buster), this problem has been fixed in version 3.2.2+debian-1+deb10u1.
