Title: PHP 'ini_restore()' Memory Information Disclosure Vulnerability
Severity: MODERATE
Description:
PHP is a programming language commonly used for web applications.
PHP is prone to an information-disclosure vulnerability that occurs in its implementation of the 'ini_restore()' function. Specifically, memory may be revealed when configuration variables set with the 'ini_set()' function are unset with the affected function. This error occurs in the 'zend_ini.c' source file.
A malicious script may exploit this issue to read from arbitrary memory locations, possibly resulting in the disclosure of sensitive information that may aid in further attacks.
