Overview
Affected versions of this package are vulnerable to Improper Validation of Array Index in the CBC-HMAC decryption process. An attacker can cause a panic and disrupt service availability by submitting specially crafted ciphertext that results in an empty buffer being passed to the unpadding routine. This is only exploitable if applications decrypt attacker-controlled ciphertext using A128CBC-HS256, A192CBC-HS384, or A256CBC-HS512 content-encryption algorithms.
