Elliptic 安全漏洞
Elliptic is a fast elliptic curve cryptographic library in javascript by the individual developer Fedor Indutny. A security vulnerability exists in Elliptic 6.6.1 and earlier versions, which stems from a miscalculation of the k-value in the ECDSA implementation and could lead to key disclosure...
PT-2026-1743
Name of the Vulnerable Software and Affected Versions Elliptic versions prior to 6.6.2 Description The ECDSA implementation within the Elliptic package produces incorrect signatures when an interim value of k calculated according to step 3.2 of RFC 6979 contains leading zeros, making it susceptib...
Medium: aws-cfn-bootstrap
Issue Overview: Issue summary: A timing side-channel which could potentially allow recovering the private key exists in the ECDSA signature computation. Impact summary: A timing side-channel in ECDSA signature computations could allow recovering the private key by an attacker. However, measuring...
UBUNTU-CVE-2022-50731
In the Linux kernel, the following vulnerability has been resolved: crypto: akcipher - default implementation for setting a private key Changes from v1: removed the default implementation from setpubkey: it is assumed that an implementation must always have this callback defined as there are no u...
CVE-2025-66016
CGGMP24 is a state-of-art ECDSA TSS protocol that supports 1-round signing requires 3 preprocessing rounds, identifiable abort, and a key refresh protocol. Prior to version 0.6.3, there is a missing check in the ZK proof that enables an attack in which single malicious signer can reconstruct full...
UBUNTU-CVE-2025-11934
Improper input validation in the TLS 1.3 CertificateVerify signature algorithm negotiation in wolfSSL 5.8.2 and earlier on multiple platforms allows for downgrading the signature algorithm used. For example when a client sends ECDSA P521 as the supported signature algorithm the server previously...

JLSEC-2025-201 An issue was discovered in Arm Mbed TLS before 2.16.6 and 2.7.x before 2.7.15
An issue was discovered in Arm Mbed TLS before 2.16.6 and 2.7.x before 2.7.15. An attacker that can get precise enough side-channel measurements can recover the long-term ECDSA private key by 1 reconstructing the projective coordinate of the result of scalar multiplication by exploiting side...
TencentOS Server 4: openssl (TSSA-2025:0640)
The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the TSSA-2025:0640 advisory. Package updates are available for TencentOS Server 4 that fix the following vulnerabilities:...
Siemens SIMATIC S7-1500 Observable Discrepancy (CVE-2019-13627)
It was discovered that there was a ECDSA timing attack in the libgcrypt20 cryptographic library. Version affected: 1.8.4-5, 1.7.6-2+deb9u3, and 1.6.3-2+deb8u4. Versions fixed: 1.8.5-2 and 1.6.3-2+deb8u7. This plugin only works with Tenable.ot. Please visit...
CVE-2025-31719
CVE-2025-31719 concerns a memory consistency issue in the TEE EcDSA algorithm that could lead to incorrect signature results with low probability. Multiple sources (Red Hat, EUVD/ENISA, NVD, CVE lists) reiterate the same description; no concrete impact specifics (affected product versions, exploi...
Astra Linux – Vulnerability in Linux 6.12
In the Linux kernel, the following vulnerability has been resolved: crypto: ecdsa – Mitigation of integer overflows in DIVROUNDUP. Herbert notes that DIVROUNDUP may cause unnecessary overflows if the -keysize callback of an ecdsa implementation returns an unusually large value. Instead, Herbert...

GHSA-FR8M-434R-G3XP gnark-crypto doesn't range check input values during ECDSA and EdDSA signature deserialization
Impact During deserialization of ECDSA and EdDSA signatures gnark-crypto did not check that the values are in the range 1, n-1 with n being the corresponding modulus either base field modulus in case of R in EdDSA, and scalar field modulus in case of s,r in ECDSA and s in EdDSA. As this also...
