Vulnerability details

The vulnerability allows a remote non-authenticated attacker to read and manipulate data.

The mb_parse_str function in PHP 4.0.0 through 4.4.6 and 5.0.0 through 5.2.1 sets the internal register_globals flag and does not disable it in certain cases when a script terminates, which allows remote attackers to invoke available PHP scripts with register_globals functionality that is not detectable by these scripts, as demonstrated by forcing a memory_limit violation.


Affected software

PHP
Gentoo Linux
dev-lang/php
