CVE-2014-6259 is a vulnerability of currently unknown severity. Zenoss Core through 5 Beta 3 does not properly detect recursion during entity expansion, which allows remote attackers to cause a denial of service (memory and CPU consumption) via a crafted XML document containing a large number of nested entity references, aka ZEN-15414, a similar issue to CVE-2003-1564.. EPSS estimates a 1.59% chance of exploitation in the next 30 days.
