nimiq-keys: Unchecked Ed25519 signature length in TaggedPublicKey::verify causes remote node panic via DHT
Impact A malicious network peer can crash any Nimiq full node by publishing a crafted Kademlia DHT record containing a TaggedSigned with a signature field whose byte length is not exactly 64. When the victim node's DHT verifier calls TaggedSigned::verify, execution reaches...
OESA-2026-2345 libgcrypt security update
Libgcrypt is a general purpose cryptographic library originally based on code from GnuPG. Security Fixes: Libgcrypt before 1.12.2 sometimes allows a heap-based buffer overflow and denial of service via crafted ECDH ciphertext to gcrypkdecrypt.CVE-2026-41989...
Nessus Network Monitor < 6.5.4 Multiple Vulnerabilities (TNS-2026-14)
According to its self-reported version, the Nessus Network Monitor running on the remote host is prior to 6.5.4. It is, therefore, affected by multiple vulnerabilities as referenced in the TNS-2026-14 advisory. - An integer overflow can be triggered in SQLite's concatws function. The resulting,...
bouncycastle: BC-JAVA: PKIX draft CompositeVerifier accepts empty signature sequence as valid
A flaw was found in Legion of the Bouncy Castle Inc. BC-JAVA bcpkix. The PKIX draft CompositeVerifier implementation improperly accepts an empty signature sequence as a valid cryptographic signature. This issue allows a remote attacker to bypass signature verification mechanisms, potentially...

OpenSSH: OpenSSH: Information disclosure due to unintended cryptographic algorithm usage
A flaw was found in OpenSSH. This vulnerability allows the system to use unintended Elliptic Curve Digital Signature Algorithm ECDSA algorithms. This occurs because the configuration for accepted public key algorithms is misinterpreted, leading to the use of weaker cryptographic methods than...
CVE-2026-42859 Neat VNC: Buffer overflow due to oversized RSA public keys
Neat VNC is a VNC server library. Prior to 0.9.6, a pre-authentication stack buffer overflow exists in neatvnc in the RSA-AES security type handler. An unauthenticated remote attacker who can reach the VNC listening socket can send a crafted security type 5 RSA-AES or security type 129 RSA-AES-25...
