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...

Astra Linux – Vulnerability in OpenSSL

Issue summary: A timing side-channel that could potentially allow the recovery of the private key exists in the ECDSA signature computation. Impact summary: A timing side-channel in ECDSA signature computations could allow an attacker to recover the private key. However, measuring the timing woul...

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 libsodium

libsodium before ad3004e, in atypical use cases involving certain custom cryptography or untrusted data, mishandles checks for whether an elliptic curve point is valid. This occurs because it sometimes allows points that are not part of the main cryptographic group...

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 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 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...
