Astra Linux – Vulnerability in mbedtls

In Mbed TLS versions prior to 2.28.10 and 3.x before 3.6.3, in some cases of failed memory allocation or hardware errors, uninitialized stack memory was used to construct the TLS Finished message. This could potentially lead to authentication bypasses, such as replay attacks...

JLSEC-2025-201 An issue was discovered in Arm Mbed TLS before 2.16.6 and 2.7.x before 2.7.15

An issue was discovered in Arm Mbed TLS before 2.16.6 and 2.7.x before 2.7.15. An attacker that can get precise enough side-channel measurements can recover the long-term ECDSA private key by 1 reconstructing the projective coordinate of the result of scalar multiplication by exploiting side...

An issue was discovered in Mbed TLS before 2.28.9 and 3.x before 3.6.1, in which the user-selected algorithm is not used. Unlike previously documented, enabling MBEDTLSPSAHMACDRBGMDTYPE does not cause the PSA subsystem to use HMACDRBG: it uses HMACDRBG only when MBEDTLSPSACRYPTOEXTERNALRNG and...

JLSEC-2025-209 An issue was discovered in Arm Mbed TLS before 2.24.0

An issue was discovered in Mbed TLS 2.x before 2.28.7 and 3.x before 3.5.2. There was a timing side channel in RSA private operations. This side channel could be sufficient for a local attacker to recover the plaintext. It requires the attacker to send a large number of messages for decryption, a...
