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 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 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 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...
