openssl: CMS AuthEnvelopedData Processing May Accept Forged Messages

A flaw was found in OpenSSL's Cryptographic Message Services CMS AuthEnvelopedData processing. An on-path attacker can exploit insufficient input validation on cipher and tag length fields by sending specially crafted CMS messages. This can lead to the forging of messages or bypassing integrity...

RUSTSEC-2026-0336 MIKEY message MAC is never verified on receive, so forged messages are accepted

mykey implements MIKEY RFC 3830 for SRTP key exchange. No receive path verified the MIKEY message authentication code. crypto::verifymac existed and was correct, but it was called only from unit tests — neither MikeyMessage::frombytes nor MikeyMessage::completepsk invoked it. newpskinit computed ...

CVE-2026-85422
