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...

[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...
