CVE-2026-50185

CVE-2026-50185 affects RustCrypto CMOV (cmov crate) aarch64 backends where Cmov and CmovEq incorrectly assume high bits are zero-extended when loading small values, causing left.cmovz and cmoveq operations to produce incorrect results under certain casts or inline-asm paths. Affected range is 0.1...

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 ...

CVE-2025-62514

Parsec’s 3.x web component libparsec_crypto (RustCrypto backend) does not verify weak order points for Curve25519 in versions before 3.6.0. An attacker in a MITM could supply weak order points to both parties during Diffie-Hellman, increasing the chance that both ends derive the same shared key a...

RustCrypto signatures: Data forgery vulnerability

RustCrypto signatures are a set of digital signature algorithms developed by RustCrypto under open source. In versions of RustCrypto signatures from 0.0.4 to 0.1.0-rc.4, there was a vulnerability related to data manipulation. This vulnerability stemmed from the signature verification implementati...
