Xerces-C++ vulnerability in Ubuntu could crash or execute code with crafted files. Update now for security.
Xerces-C++ could be made to crash or run programs if it opened a specially crafted file.

Summary

Xerces-C++ could be made to crash or run programs if it opened a specially

crafted file.

Software Description:

- xerces-c: Validating XML parser written in a portable subset of C++

Details:

USN-6579-1 fixed a vulnerability in Xerces-C++. This update provides the

corresponding update for Ubuntu 20.04 LTS, Ubuntu 22.04 LTS, Ubuntu 23.04

and Ubuntu 23.10.

Original advisory details:

It was discovered that Xerces-C++ was not properly handling memory

management operations when parsing XML data containing external DTDs,

which could trigger a use-after-free error. If a user or automated system

were tricked into processing a specially crafted XML document, an attacker

could possibly use this issue to cause a denial of service or execute

arbitrary code.
