What is CVE-2023-39615?

An out-of-bounds read vulnerability exists within Libxml2, specifically in the xmlSAX2StartElement() function. This flaw permits attackers to trigger a Denial of Service (DoS) by providing a specially crafted XML file. It is important to note that despite the vendor's stance that the legacy SAX1 interface with custom callbacks is unsupported, crashes can occur even without any tailored input.
