PHP memory_limit and strip_tags() vulnerabilities


Stefan Esser has reported two vulnerabilities in PHP, which can be exploited by malicious people to bypass security functionality or compromise a vulnerable system. An error within PHP's memory_limit request termination allows remote code execution on PHP servers with activated memory_limit. A binary safety problem within PHP's strip_tags() function may allow injection of arbitrary tags in Internet Explorer and Safari browsers.
