Bugzilla: 649056: CVE-2010-3870 php: XSS mitigation bypass via utf8_decode()

Details

The MITRE CVE dictionary describes this issue as:

The utf8_decode function in PHP before 5.3.4 does not properly handle non-shortest form UTF-8 encoding and ill-formed subsequences in UTF-8 data, which makes it easier for remote attackers to bypass cross-site scripting (XSS) and SQL injection protection mechanisms via a crafted string.
