Name of the Vulnerable Software and Affected Versions jabberd14 versions 1.6.1.1 and earlier

Description The issue allows remote attackers to cause a denial of service due to memory and CPU consumption. This is achieved through a crafted XML document containing a large number of nested entity references, which the software does not properly detect during recursion.

Recommendations For jabberd14 versions 1.6.1.1 and earlier, consider restricting the size and complexity of incoming XML documents to prevent excessive resource consumption until a proper fix is applied. As a temporary workaround, limiting the number of nested entity references in XML documents may help mitigate the risk of denial of service attacks.
