[openssl-dev] [openssl.org #4656] [BUG] print_bin could access memory off the end of a buffer

[Perrow, Graeme via RT]

In file crypto/ec/eck_prn.c, if the function print_bin is called with len >= 15 and off >= 124, we would eventually hit line 261:

memset( &(str[1]), ' ', off + 4 );

which would write >= 128 bytes into a 127-byte buffer.
