PBES2-HS*+A*KW unwrap accepts an unbounded p2c iteration count, enabling CPU-amplification denial of service

Impact When a JWE uses a password-based key-encryption algorithm PBES2-HS256+A128KW, PBES2-HS384+A192KW, PBES2-HS512+A256KW, PBES2AESKW::unwrapKey reads the p2c PBKDF2 iteration count parameter directly from the attacker-controlled JOSE header and passes it to hashpbkdf2 with no upper bound. The...

openssl: Out-of-bounds read & write in RFC 3211 KEK Unwrap

A flaw was found in the OpenSSL CMS implementation RFC 3211 KEK Unwrap. This vulnerability allows memory corruption, an application level denial of service, or potential execution of attacker-supplied code via crafted CMS messages using password-based encryption PWRI...

JLSEC-2026-266

Issue summary: An application trying to decrypt CMS messages encrypted using password based encryption can trigger an out-of-bounds read and write. Impact summary: This out-of-bounds read may trigger a crash which leads to Denial of Service for an application. The out-of-bounds write can cause a...
