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...

CGGMP21 presignatures can be used in the way that significantly reduces security

This attack is against presignatures used in very specific context: Presignatures + HD wallets derivation: security level reduces to 85 bits \ Previously you could generate a presignature, and then choose a HD derivation path while issuing a partial signature via Presignature::setderivationpath,...

CVE-2025-63353

FiberHome GPON ONU HG6145F1 RP4423 is affected. The vulnerability arises from a deterministic algorithm that derives the device’s default WPA/WPA2 pre‑shared key from the SSID, enabling an observer to predict the router password without authentication. Red Hat and other sources corroborate that t...

Signal’s Post-Quantum Cryptographic Implementation

Signal has just rolled out its quantum-safe cryptographic implementation. Ars Technica has a really good article with details: Ultimately, the architects settled on a creative solution. Rather than bolt KEM onto the existing double ratchet, they allowed it to remain more or less the same as it ha...
