Name of the Vulnerable Software and Affected Versions ezXML versions 0.8.3 through 0.8.6

Description The issue is related to the ezxml ent ok() function, which mishandles recursion. This can lead to stack consumption when processing a crafted XML file, potentially allowing a remote attacker to cause a denial of service.
