Astra Linux – Vulnerability in OpenSSL

There exists a timing-based side channel in the OpenSSL RSA Decryption implementation. This vulnerability could be sufficient for an attacker to recover plaintext across a network in a Bleichenbacher-style attack. To successfully decrypt data, an attacker would need to be able to send a very larg...

Astra Linux – Vulnerability in python-cryptography

Python-Cryptography 3.2 is vulnerable to Bleichenbacher timing attacks in the RSA decryption API, due to timed processing of valid PKCS1 v1.5 ciphertext...

Astra Linux – Vulnerability in nss

The NSS code used for checking PKCS1 v1.5 was leaking information useful for launching Bleichenbacher-style attacks. Both the overall correctness of the padding and the length of the encrypted message were exposed through timing side-channels. By sending a large number of ciphertexts selected by...
