Astra Linux - уязвимость в mbedtls
In Arm Mbed TLS before version 2.19.0, and Arm Mbed Crypto before version 2.0.0, when deterministic ECDSA is enabled, an RNG with insufficient entropy is used for blinding. This may allow an attacker to recover a private key through side-channel attacks if a victim signs the same message multiple...

Arm Mbed TLS before 2.19.0 and Arm Mbed Crypto before 2.0.0, when deterministic ECDSA is enabled, use an RNG with insufficient entropy for blinding, which might allow an attacker to recover a private key via side-channel attacks if a victim signs the same message many times. (For Mbed TLS, the fix is also available in versions 2.7.12 and 2.16.3.)
