Summary
php-pear in php5 contains CWE-502 (Deserialization of Untrusted Data) and CWE-915 (Improperly Controlled Modification of Dynamically-Determined Object Attributes) vulnerabilities in its Archive_Tar class. When extract is called without a specific prefix path, can trigger unserialization by crafting a tar file with `phar://[path_to_malicious_phar_file]` as path. Object injection can be used to trigger destruct in the loaded PHP classes, all with possible remote code execution that can result in files being deleted or possibly modified.
