Description
Multiple format string vulnerabilities in phar_object.c in the phar extension in PHP 5.3.5 and earlier allow context-dependent attackers to obtain sensitive information from process memory, cause a denial of service (memory corruption), or possibly execute arbitrary code via format string specifiers in an argument to a class method, leading to an incorrect zend_throw_exception_ex call.

Remediation
Red Hat statement
Red Hat does not consider this flaw to be a security issue. It is improbable that a script would accept untrusted user input or unvalidated script input data as a PHAR archive file name to load. The file name passed to the PHAR-handling functions is therefore under the full control of the script author and no trust boundary is crossed.
