Description Huzaifa S. Sidhpurwala 2014-07-21 05:09:23 UTC
Mozilla security researcher Christian Holler discovered several issues while fuzzing the parsing of SSL certificates. Two of these issues were a result of using characters that are not UTF-8 in certificates when various functions expected all strings to be UTF-8 format. The third issue was a result of using characters that were not ASCII in certificates while a function expected only ASCII formatted text. All of these issues causes the certificates to be incorrectly parsed, leading to a potential inability to use valid SSL certificates.
