Description Huzaifa S. Sidhpurwala 2015-12-15 03:36:34 EST
Security researcher musicDespiteEverything reported an issue when ASCII code 11 for vertical tab is stored in a cookie in violation of RFC6265. This may result in incorrect cookie handling by servers, resulting in the potential ability to set cookie values and read cookie data from users in concert with some web servers if the vertical tab character is mishandled during parsing.
