Description Adam Mariš 2016-07-25 13:37:30 UTC 
Calling to uloc_acceptLanguageFromHTTP with parameter size "httpAcceptLanguage" equal or greater than ULOC_FULLNAME_CAPACITY + 1, the local variable "tmp" might leave unterminated. uloc_acceptLanguageFromHTTP doesn’t check status result after call to uloc_canonicalize. This might cause stack data leak.
