CVE-2015-8835 php: type confusion issue in Soap Client call() method
Last modified: 2016-11-15 09:24:40 EST
SoapClient's __call() method suffers from multiple type confusion issues which could be used to exfiltrate arbitrary memory contents or cause crashe via unsafe unserialize() calls. A new CVE was assigned for the first part of the following bug: https://bugs.php.net/bug.php?id=70081 References: http://seclists.org/oss-sec/2016/q1/695 Upstream fix: https://git.php.net/?p=php-src.git;a=commitdiff;h=c96d08b27226193dd51f2b50e84272235c6aaa69
This issue happens when untrusted input is unserialized. Doing so it documented as being unsafe: http://php.net/manual/en/function.unserialize.php Do not pass untrusted user input to unserialize(). Unserialization can result in code being loaded and executed due to object instantiation and autoloading, and a malicious user may be able to exploit this. Use a safe, standard data interchange format such as JSON (via json_decode() and json_encode()) if you need to pass serialized data to the user. Affected code is part of the SOAP extension. In Red Hat products, this extension is packaged separately in the php-soap subpackages. Systems without php-soap installed can not be affected by this issue. Removal of the package can be used to mitigate the issue on systems that do not require SOAP extension.
