Name of the Vulnerable Software and Affected Versions ezXML version 0.8.6

Description The issue is related to the ezxml decode() function in the ezXML library, which performs incorrect memory handling while parsing crafted XML files. This leads to a heap out-of-bounds read, allowing a remote attacker to cause a denial of service using a specially crafted XML file.

Recommendations For ezXML version 0.8.6, as a temporary workaround, consider disabling the ezxml decode() function until a patch is available. Restrict access to the ezXML library to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
