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...

netty-incubator-codec-ohttp's HPKEContext operations may produce empty byte[] on failures

HKDFexpand: returns non-NULL on failure. The byte is filled with zeros and has no way to distinguish success from failure. Since this output is used as HKDF key material for the response AEAD, a failure silently produces an all-zero key. When EVPHPKECTXexport fails it also returns an empty byte...

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...
