gnutls: timing side-channel in the TLS RSA key exchange code

A timing side-channel vulnerability was found in RSA ClientKeyExchange messages in GnuTLS. This side-channel may be sufficient to recover the key encrypted in the RSA ciphertext across a network in a Bleichenbacher style attack. To achieve a successful decryption, the attacker would need to send ...

Security Advisory Description The dsasignsetup function in crypto/dsa/dsaossl.c in OpenSSL through 1.0.2h does not properly ensure the use of constant-time operations, which makes it easier for local users to discover a DSA private key via a timing side-channel attack. CVE-2016-2178 Impact An...

K43741620: OpenSSL vulnerabilities CVE-2018-0734 and CVE-2018-0735

Security Advisory Description CVE-2018-0734 The OpenSSL DSA signature algorithm has been shown to be vulnerable to a timing side channel attack. An attacker could use variations in the signing algorithm to recover the private key. Fixed in OpenSSL 1.1.1a Affected 1.1.1. Fixed in OpenSSL 1.1.0j...

A timing side-channel in the handling of RSA ClientKeyExchange messages was discovered in GnuTLS. This side-channel can be sufficient to recover the key encrypted in the RSA ciphertext across a network in a Bleichenbacher style attack. To achieve a successful decryption the attacker would need to send a large amount of specially crafted messages to the vulnerable server. By recovering the secret from the ClientKeyExchange message the attacker would be able to decrypt the application data exchanged over that connection.
