Description

The SoapClient __call method in ext/soap/soap.c in PHP before 5.4.45, 5.5.x before 5.5.29, and 5.6.x before 5.6.13 does not properly manage headers, which allows remote attackers to execute arbitrary code via crafted serialized data that triggers a "type confusion" in the serialize_function_call function.

Affected products

PHP: through 5.4.44; 5.5.0, 5.5.0-alpha1, 5.5.0-alpha2, 5.5.0-alpha3, 5.5.0-alpha4, 5.5.0-alpha5 (+53)
