CVE-2016-3185: The make_http_soap_request function in ext/soap/php_http.c in PHP before 5.4.44, 5.5.x before 5.5.28, 5.6.x...

Security readout for executives and security teams

CVE-2016-3185 affects PHP's SOAP client code in older PHP releases. A crafted serialized cookie value can make PHP expose sensitive process memory or crash the application. The business risk is highest for legacy PHP services still using the SOAP extension, especially where attacker-controlled data can reach SOAP client calls. Exposure is likely limited to legacy PHP deployments with ext/soap enabled and applications using SoapClient. Systems on maintained vendor PHP packages from Ubuntu or SUSE may have received patched builds, but version and package status must be verified. Prioritize remediation where legacy PHP SOAP functionality remains internet-facing or business-critical. The vulnerability can expose memory or cause outages, but supplied sources do not show active exploitation. Modernized or patched PHP stacks should be lower priority after verification. Mitigation focus: Upgrade PHP beyond the fixed versions named in the CVE record.; Apply vendor PHP security updates from Ubuntu, SUSE, or the relevant distribution.; Disable the PHP SOAP extension where it is not required..
