Description Josh Bressers 2010-12-06 19:23:06 UTC
Security researchers Yosuke Hasegawa and Masatoshi Kimura reported that the
x-mac-arabic, x-mac-farsi and x-mac-hebrew character encodings are
vulnerable to XSS attacks due to some characters being converted to angle
brackets when displayed by the rendering engine. Sites using these
character encodings would thus be potentially vulnerable to script
injection attacks if their script filtering code fails to strip out these
specific characters.
