Description Huzaifa S. Sidhpurwala 2012-04-22 06:26:14 UTC

Anne van Kesteren of Opera Software found a multi-octet encoding issue where certain octets will destroy the following octets in the processing of some multibyte character sets. This can leave users vulnerable to cross-site scripting (XSS) attacks on maliciously crafted web pages.
