Description

PHP contains a flaw that may allow a context-dependent attacker to gain elevated privileges. The issue is due to the str_replace function not sanitizing user-supplied input. If an attacker supplies a single character search string in conjunction with a long replacement string, they can trigger an overflow and execute arbitrary code.

Attack Type: Input Manipulation
Impact: Loss of Integrity
