Allocation of Resources Without Limits or Throttling

Overview Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling via unbounded processing of the p2c parameter in PBES2 JWE decryption. An attacker can cause denial of service by supplying a crafted JWE containing an excessively large p2c value in...

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...
