A vulnerability was found in Apple Mac OS X up to 10.9.4 (Operating System) and classified as critical. This issue affects an unknown code of the component apache_mod_php. The manipulation with an unknown input leads to a symlink vulnerability. Using CWE to declare the problem leads to CWE-61. The product, when opening a file or directory, does not sufficiently account for when the file is a symbolic link that resolves to a target outside of the intended control sphere. This could allow an attacker to cause the product to operate on unauthorized files. Impacted is confidentiality, integrity, and availability. The summary by CVE is:
The SPL component in PHP before 5.4.30 and 5.5.x before 5.5.14 incorrectly anticipates that certain data structures will have the array data type after unserialization, which allows remote attackers to execute arbitrary code via a crafted string that triggers use of a Hashtable destructor, related to "type confusion" issues in (1) ArrayObject and (2) SPLObjectStorage.
The weakness was released 09/17/2014 as HT6443 as confirmed advisory (Website). It is possible to read the advisory at support.apple.com.

No form of authentication is needed for a successful exploitation. Technical details are unknown but a public exploit is available.
A public exploit has been developed by SEC Consult and been published 3 years after the advisory. The exploit is available at exploit-db.com. It is declared as proof-of-concept. We expect the 0-day to have been worth approximately $5k-$25k.
