Description
This security bulletin contains information about 3 secuirty vulnerabilities.
1) Padding oracle attack (CVE-ID: CVE-2019-1563)
The vulnerability allows a remote attacker to perform padding oracle attack.
The vulnerability exists due to possibility to perform a Bleichenbacher padding oracle attack against the RSA key, in situations where an attacker receives automated notification of the success or failure of a decryption attempt an attacker. A remote attacker can send a very large number of messages to be decrypted, can recover a CMS/PKCS7 transported encryption key or decrypt any RSA encrypted message that was encrypted with the public RSA key.
2) Protection Mechanism Failure (CVE-ID: CVE-2019-1549)
The vulnerability allows a remote attacker to bypass certain security restrictions.
The vulnerability exists due to OpenSSL does not use by default a rewritten random number generator (RNG) in the event of a fork() system call, resulting in the child and parent processes share the same RNG state.
3) Cryptographic issues (CVE-ID: CVE-2019-1547)
The vulnerability allows a remote attacker to decrypt traffic.
The vulnerability exists due to insufficient enforcement of side channel resistant code paths. A remote attacker with ability to create a large number of signatures, where explicit parameters with no co-factor is present, can force the application to fall back to non-side channel resistant code pathsduring ECDSA signature operation and perform full key recovery.
Successful exploitation of the vulnerability may allow an attacker to decrypt communication between server and client.
