elliptic is suffers from ECDSA signature malleability. The vulnerability exists as it fails to ensure that the following tests produces different results, long form encoding of length of sequence, length of sequence contains leading 0, length of integer contains leading 0, uint32 overflow in length of integer, uint64 overflow in length of integer, prepending 0's to integer, and long form encoding of length of integer.
