Name of the Vulnerable Software and Affected Versions libxml2 versions prior to 2.9.5

Description The issue is related to a buffer overflow in the xmlmemory.c component of the libxml2 software for XML document analysis. This can be exploited by a remote attacker to access confidential data, compromise its integrity, and cause a denial of service. An integer overflow in xmlmemory.c allows a remote attacker to potentially exploit heap corruption via a crafted XML file.

Recommendations For libxml2 versions prior to 2.9.5, update to version 2.9.5 or later to resolve the issue. As a temporary workaround, consider restricting the use of the xmlmemory.c component until a patch is available. Avoid using crafted XML files that could exploit the integer overflow in xmlmemory.c until the issue is resolved.
