RustCrypto Has Insufficient Length Validation in decrypt() in SM2-PKE

Summary A denial-of-service vulnerability exists in the SM2 public-key encryption PKE implementation: the decrypt path performs unchecked slice::splitat operations on input buffers derived from untrusted ciphertext. An attacker can submit short/undersized ciphertext or carefully-crafted DER-encod...
