CVE-2009-5016Date: (C)2010-11-12   (M)2018-02-19


Integer overflow in the xml_utf8_decode function in ext/xml/xml.c in PHP before 5.2.11 makes it easier for remote attackers to bypass cross-site scripting (XSS) and SQL injection protection mechanisms via a crafted string that uses overlong UTF-8 encoding, a different vulnerability than CVE-2010-3870.
