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 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 libsodium
