F5 Networks BIG-IP : PHP vulnerability (K13588)

medium Nessus Plugin ID 78135


The remote device is missing a vendor-supplied security patch.


PHP versions prior to 5.3.9 compute hash values for form parameters without restricting the ability to trigger hash collisions predictably, which may allow remote attackers to cause a denial of service (DoS) (CPU consumption) by sending many crafted parameters.


Upgrade to one of the non-vulnerable versions listed in the F5 Solution K13588.
