Name of the Vulnerable Software and Affected Versions libxml2 versions prior to 2.9.4

Description The issue is related to a heap-based buffer over-read in the xmlNextChar function, allowing remote attackers to cause a denial of service. It may also lead to arbitrary code execution or memory damage through a specially crafted XML document.

Recommendations For versions prior to 2.9.4, update to version 2.9.4 or later to resolve the issue. As a temporary workaround, consider restricting the use of the xmlNextChar function until a patch is available. Avoid processing untrusted XML documents with the affected libxml2 versions to minimize the risk of exploitation.
