Description
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.
Affected configurations
• php php (< 5.2.14)
• php php (>= 5.3.0 < 5.3.4)
• canonical ubuntu linux 6.06
• canonical ubuntu linux 8.04
• canonical ubuntu linux 9.10
• canonical ubuntu linux 10.04
• canonical ubuntu linux 10.10
