CVE-2009-4142

原文の説明

The htmlspecialchars function in PHP before 5.2.12 does not properly handle (1) overlong UTF-8 sequences, (2) invalid Shift_JIS sequences, and (3) invalid EUC-JP sequences, which allows remote attackers to conduct cross-site scripting (XSS) attacks by placing a crafted byte sequence before a special character.

影響を受けるソフトウェア

• PHP = 5.0.2= 4.3.5= 2.0b10= 3.0.16= 5.1.3= 4.4.7 完全一致
