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.

Affected products

PHP: through 5.3.5; 1.0, 2.0, 2.0b10, 3.0, 3.0.1, 3.0.2 (+97)
