Description Huzaifa S. Sidhpurwala 2012-11-17 11:55:11 UTC 
Security researcher Masato Kinugawa found when HZ-GB-2312 charset encoding is used for text, the "~" character will destroy another character near the chunk delimiter. This can lead to a cross-site scripting (XSS) attack in pages encoded in HZ-GB-2312.
