USN-6579-1: Xerces-C++ vulnerability
11 January 2024
Xerces-C++ could be made to crash or run programs if it opened a specially crafted file.
Releases
Packages
- xerces-c - Validating XML parser written in a portable subset of C++
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.

The problem can be corrected by updating your system to the following package versions:
