ROOT-APP-NPM-GHSA-VJH7-7G9H-FJFH GHSA-vjh7-7g9h-fjfh in elliptic - Patched by Root
Root has patched GHSA-vjh7-7g9h-fjfh in the elliptic package for Root:npm. Multiple fixed versions available...
Astra Linux – Vulnerability in nss
When performing EC scalar point multiplication, the wNAF point multiplication algorithm was used; this resulted in the leakage of partial information regarding the nonce used during signature generation. Given an electro-magnetic trace from several generations of signatures, the private key could...
Astra Linux – Vulnerability in Node-Elliptic
The verify function in lib/elliptic/eddsa/index.js within the Elliptic package, as of version 6.5.6 for Node.js, omits the validation of the condition “sig.S.gtesig.eddsa.curve.n || sig.S.isNeg”...
Astra Linux – Vulnerability in mbedtls
A issue was discovered in Arm Mbed TLS before version 2.23.0. A side channel allows the recovery of an ECC private key, which is related to functions such as mbedtlsecpcheckpubpriv, mbedtlspkparsekey, mbedtlspkparsekeyfile, mbedtlsecpmul, and mbedtlsecpmulrestartable...
Astra Linux – Vulnerability in mbedtls
The ECDSA signature implementation in ecdsa.c in Arm Mbed Crypto 2.1 and Mbed TLS from 2.19.1 onwards does not reduce the blinded scalar before computing the inverse. This allows a local attacker to recover the private key through side-channel attacks...
Astra Linux – Vulnerability in Golang-1.15
In Go versions before 1.14.14 and 1.15.x, as well as before 1.15.7, the crypto/elliptic/p224.go file may generate incorrect outputs due to a underflow of the lowest limb during the final complete reduction of the P-224 field...
Astra Linux – Vulnerability in Nettle
A flaw was discovered in Nettle versions prior to 3.7.2. In these versions, several Nettle signature verification functions—GOST DSA, EDDSA, and ECDSA—result in the Elliptic Curve Cryptography point ECC’s multiply function being called with out-of-range scalers. This may lead to incorrect results...
Astra Linux – Vulnerability in Node-Elliptic
The Elliptic package 6.5.7 for Node.js, in its ECDSA implementation, does not correctly verify valid signatures when the hash contains at least four leading 0 bytes, and when the order of the elliptic curve’s base point is smaller than the hash, due to an truncateToN anomaly. This results in vali...
Astra Linux – Vulnerability in OpenSSL
Issue summary: Use of the low-level GF2^m elliptic curve APIs with untrusted explicit values for the field polynomial can lead to out-of-bounds memory reads or writes. Impact summary: Out-of-bound memory writes can cause the application to crash or even lead to remote code execution. However, in...
Astra Linux – Vulnerability in libgcrypt20
It was discovered that there was an ECDSA timing attack in the libgcrypt20 cryptographic library. Affected versions: 1.8.4-5, 1.7.6-2+deb9u3, and 1.6.3-2+deb8u4. Fixed versions: 1.8.5-2 and 1.6.3-2+deb8u7...
Astra Linux – Vulnerability in Firefox, NSS
When the memory resources are nearly exhausted, an elliptic curve key that was never allocated can be reclaimed. This vulnerability affects Firefox 128 and Thunderbird 128...
OSEC-2026-15 EC public key out of bounds read
The internal Point.ofoctets function is missing a length check for compressed points, and thus is raising an exception when a short buffer is provided. This affects all NIST curves P-256, P-384, P-521 and both Dsa.pubofoctets and Dh.keyexchange functions. Fix The fix is to check the length of the...
