CVE-2026-81687 openssl_encrypt before 1.4.9 Denial of Service via KDF

opensslencrypt versions before 1.4.9 fail to enforce a time ceiling on key derivation function iteration counts specified in file metadata. Attackers can craft files with extremely high KDF iteration counts to consume CPU resources for unbounded periods before password verification occurs...

Allocation of Resources Without Limits or Throttling

Overview Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling in PKCS12KeyStoreSpi, which feeds the attacker-controlled KDF iteration count from a PKCS12 file's MAC data and encrypted bags into key derivation during engineLoad without enforcing...

Allocation of Resources Without Limits or Throttling

Overview Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling in JcePKCSPBEInputDecryptorProviderBuilder and JceOpenSSLPKCS8DecryptorProviderBuilder, which parse PBES2Parameters from attacker-supplied EncryptedPrivateKeyInfo, PKCS12, or CMS...

Allocation of Resources Without Limits or Throttling

Overview Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling in the PKMACValueVerifier.isValid and ProtectedPKIMessage.verify verification paths, where PKMACBuilder's default constructor leaves maxIterations = 0 and disables the iteration-count...

PYSEC-2026-2529 joserfc's PBES2 p2c Unbounded Iteration Count enables Denial of Service (DoS)

Summary A resource exhaustion vulnerability in joserfc allows an unauthenticated attacker to cause a Denial of Service DoS via CPU exhaustion. When the library decrypts a JSON Web Encryption JWE token using Password-Based Encryption PBES2 algorithms, it reads the p2c PBES2 Count parameter directl...

RUSTSEC-2026-0179 Unbounded SCRAM iteration count allows a malicious server to cause CPU-exhaustion denial of service

A malicious, compromised, or man-in-the-middle server can supply an arbitrarily large SCRAM-SHA-256 PBKDF2 iteration count during authentication. The client runs it inline with no upper bound, pinning a tokio worker thread for minutes per connection, possibly stalling the whole async runtime...

CVE-2026-11790 389-ds-base: 389-ds-base: pbkdf2 password storage plugin unbounded iteration count denial of service

A flaw was found in 389 Directory Server. The PBKDF2-SHA256 password storage plugin does not enforce an upper bound on the iteration count extracted from stored password hashes. A privileged attacker who can modify a user's password hash can cause excessive CPU consumption during authentication,...

389 Directory Server 资源管理错误漏洞

389 Directory Server is an open-source implementation of a highly available, fully functional, reliable, and secure LDAP server. There is a resource management vulnerability in 389 Directory Server. This vulnerability stems from the fact that the PBKDF2-SHA256 password storage plugin does not...

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.
