USN-6579-1: Xerces-C++ vulnerability
First published: Thu Jan 11 2024(Updated: )
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.
