Description Adam Mariš 2015-09-07 12:33:27 UTC
HAVAL pads a string with a wrong pad length, if the remaining string is over 64 and under 118 bytes length. The suspect code is:

index = (unsigned int) ((context->count[0] >> 3) & 0x3f);

When the string is over 64 and under 118 then it seems to have a wrong padding length.
