CVE-2026-17508 Password-based KDF cost parameters honoured unbounded from untrusted input across the remaining PBE entry points

In Bouncy Castle for Java before 1.86, several password-based key derivation entry points ran the KDF with cost parameters taken from the untrusted input being processed, without bounding them, so a small input could dictate an arbitrary amount of work before any password or integrity check could...

CVE-2026-81721 openssl_encrypt before 1.4.9 Denial of Service via KDF

opensslencrypt before 1.4.9 fails to validate KDF cost parameters in encrypted file metadata and keystore headers, allowing attackers to trigger unbounded memory allocation. Attackers can craft malicious encrypted files declaring arbitrarily large Argon2, scrypt, or balloon KDF parameters to...

CVE-2026-81721

openssl_encrypt before 1.4.9 fails to validate KDF cost parameters (Argon2, scrypt, or balloon) in encrypted file metadata and keystore headers. An unauthenticated attacker over the network can craft a malicious encrypted file declaring arbitrarily large KDF parameters, triggering unbounded memor...

CVE-2026-81699

openssl_encrypt versions before 1.4.9 fail to properly validate key derivation function (KDF) costs in crafted files. An attacker can supply a malicious file with excessive KDF parameters over the network with no privileges required , triggering unbounded memory and CPU exhaustion during pre-auth...

CVE-2026-58063

A flaw was found in Bouncy Castle for Java. A remote attacker can exploit this vulnerability by providing a specially crafted BCFKS keystore file that specifies an unbounded Key Derivation Function KDF cost. This can lead to a Denial of Service DoS as the system attempts to process the file,...

CVE-2026-15055

A flaw was found in Bouncy Castle for Java. An attacker could exploit this vulnerability by providing a specially crafted input to the PKCS8 / PBES2 decryptors. This input could specify an excessively high Key Derivation Function KDF cost, causing the decryptor to consume significant computationa...
