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 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...
