Missing Cryptographic Step

Overview Affected versions of this package are vulnerable to Missing Cryptographic Step in the AES-SIV RFC 5297 and AES-GCM-SIV RFC 8452 provider cipher implementations. An attacker can forge an empty message with arbitrary AAD under a key they do not know, because the expected tag is computed on...

Covert Channel

Overview Affected versions of this package are vulnerable to Covert Channel information exposure from CMSdecrypt and PKCS7decrypt. An attacker who can supply CMS or S/MIME messages and observe the application's error code and/or decryption output can use the victim's process as an adaptive chosen...
