BIT-JAVA-MIN-2025-0509 Signing Checks Bypass

A security issue was found in Sparkle before version 2.6.4. An attacker can replace an existing signed update with another payload, bypassing Sparkle’s EdDSA signing checks...

CVE-2026-5194

Missing hash/digest size and OID checks allow digests smaller than allowed when verifying ECDSA certificates, or smaller than is appropriate for the relevant key type, to be accepted by signature verification functions. This could lead to reduced security of ECDSA certificate-based authentication...

CVE-2026-5194 wolfSSL ECDSA Certificate Verification

Missing hash/digest size and OID checks allow digests smaller than allowed when verifying ECDSA certificates, or smaller than is appropriate for the relevant key type, to be accepted by signature verification functions. This could lead to reduced security of ECDSA certificate-based authentication...

AZL-50322 CVE-2024-48949 affecting package reaper for versions less than 3.1.1-13

The verify function in lib/elliptic/eddsa/index.js in the Elliptic package before 6.5.6 for Node.js omits "sig.S.gtesig.eddsa.curve.n || sig.S.isNeg" validation...

UBUNTU-CVE-2024-42459

In the Elliptic package 6.5.6 for Node.js, EDDSA signature malleability occurs because there is a missing signature length check, and thus zero-valued bytes can be removed or appended...

bind: memory leaks in EdDSA DNSSEC verification code

A flaw was found in the Bind package, where the DNSSEC verification code for the EdDSA algorithm leaks memory when there is a signature length mismatch. By spoofing the target resolver with responses that have a malformed EdDSA signature, an attacker can trigger a small memory leak, resulting in...

nettle: Out of bounds memory access in signature verification

A flaw was found in Nettle, where several Nettle signature verification functions GOST DSA, EDDSA & ECDSA result in the Elliptic Curve Cryptography point ECC multiply function being called with out-of-range scalers, possibly resulting in incorrect results. This flaw allows an attacker to force an...

UBUNTU-CVE-2017-9526

In Libgcrypt before 1.7.7, an attacker who learns the EdDSA session key from side-channel observation during the signing process can easily recover the long-term secret key. 1.7.7 makes a cipher/ecc-eddsa.c change to store this session key in secure memory, to ensure that constant-time point...
