CVE-2026-34875

An issue was discovered in Mbed TLS through 3.6.5 and TF-PSA-Crypto 1.0.0. A buffer overflow can occur in public key export for FFDH keys...

CVE-2026-34872

An issue was discovered in Mbed TLS 3.5.x and 3.6.x through 3.6.5 and TF-PSA-Crypto 1.0. There is a lack of contributory behavior in FFDH due to improper input validation. Using finite-field Diffie-Hellman, the other party can force the shared secret into a small set of values lack of contributor...

CVE-2026-3230

A flaw was found in wolfSSL. A remote attacker could exploit a missing cryptographic step in the Transport Layer Security TLS 1.3 client HelloRetryRequest handshake logic. By sending a crafted HelloRetryRequest followed by a ServerHello message that omits the required keyshare extension, an...

EUVD-2026-13209

Missing required cryptographic step in the TLS 1.3 client HelloRetryRequest handshake logic in wolfSSL could lead to a compromise in the confidentiality of TLS-protected communications via a crafted HelloRetryRequest followed by a ServerHello message that omits the required keyshare extension,...

CVE-2026-3230

wolfSSL’s TLS 1.3 client logic is affected by an improper key_share handling during HelloRetryRequest, allowing a crafted HelloRetryRequest followed by a ServerHello without the key_share extension to derive predictable traffic secrets from the (EC)DHE shared secret. Affected component: TLS hands...

Botan is a C++ library of cryptographic algorithms, including AES, DES, SHA-1, RSA, DSA, Diffie-Hellman, and many others. It also supports X.509 certificates and CRLs, and PKCS 10 certificate requests, and has a high level filter/pipe message processing system. The library is easily portable to...

CIRCL has an incorrect calculation in secp384r1 CombinedMult

The CombinedMult function in the CIRCL ecc/p384 package secp384r1 curve produces an incorrect value for specific inputs. The issue is fixed by using complete addition formulas. ECDH and ECDSA signing relying on this curve are not affected. The bug was fixed in v1.6.3...

RUSTSEC-2026-0072 Missing Check for All-Zero X25519 Shared Secret

Computing an X25519 shared secret with x25519dalek::StaticSecret::diffiehellman does not include the check that the key exchange was contributory, i.e. does not ensure on its own that the resulting shared secret is non-zero. Impact RFC 9180 mandates that implementations of HPKE must check for all...

CVE-2025-62514

Parsec is a cloud-based application for cryptographically secure file sharing. In versions on the 3.x branch prior to 3.6.0, libparseccrypto, a component of the Parsec application, does not check for weak order point of Curve25519 when compiled with its RustCrypto backend. In practice this means ...
