openssl: Possible NULL Dereference in Password-Based CMS Decryption

A flaw was found in OpenSSL. A remote attacker could exploit a NULL pointer dereference vulnerability in the Cryptographic Message Syntax CMS decryption process by providing a specially crafted password-encrypted CMS message. This occurs because the keyDerivationAlgorithm field, which is optional...

CVE-2026-42766

Issue summary: A specially crafted password-encrypted CMS message can trigger a NULL pointer dereference during CMS decryption. Impact summary: This NULL pointer dereference leads to an application crash and a Denial of Service. The CMS PasswordRecipientInfo.keyDerivationAlgorithm field is define...

jdbc.postgresql.org: pgjdbc: Client-side Denial of Service via malicious SCRAM-SHA-256 authentication

A flaw was found in pgjdbc, an open-source PostgreSQL JDBC Driver. A malicious server can exploit this vulnerability by instructing the driver to perform SCRAM-SHA-256 Salted Challenge Response Authentication Mechanism Secure Hash Algorithm 256 authentication with an excessively large iteration...

libssh: Incorrect Return Code Handling in ssh_kdf() in libssh

A flaw was found in libssh versions built with OpenSSL versions older than 3.0, specifically in the sshkdf function responsible for key derivation. Due to inconsistent interpretation of return values where OpenSSL uses 0 to indicate failure and libssh uses 0 for success—the function may mistakenl...

CVE-2026-6729

HKUDS OpenHarness prior to PR 159 remediation contains a session key derivation vulnerability that allows authenticated participants in shared chats or threads to hijack other users' sessions by exploiting a shared ohmo session key that lacks sender identity verification. Attackers can reuse...

[SECURITY] Fedora 44 Update: perl-Crypt-Argon2-0.031-1.fc44

This module implements the Argon2 key derivation function, which is suitable to convert any password into a cryptographic key. This is most often used to for secure storage of passwords but can also be used to derive a encryption key from a password. It offers variable time and memory costs as we...
