Overview
Affected versions of this package are vulnerable to Out-of-bounds Read in the SM2 decryption process due to improper validation of the encoded C3 hash field length prior to comparison. An attacker can cause a heap buffer over-read, potentially leading to a crash or other undefined behavior, by submitting a specially crafted invalid ciphertext.
