Descriptions

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.

La función htmlspecialchars en PHP versiones anteriores a v5.2.12 no maneja adecuadamente (1) secuencias UTF-8 demasiado largas, (2) secuencias inválidas Shift_JIS, y (39 secuencias inválidas EUC-JP, permitiendo a atacantes remotos dirigir ataques de secuencias de comandos en sitios cruzados (XSS) poniendo secuencias de bytes modificados antes de un carácter especial.
