CVE-2018-16868

CVE-2018-16868 concerns a Bleichenbacher-type side-channel padding oracle in GnuTLS during PKCS#1 v1.5 RSA verification. The provided documents indicate this affects GnuTLS across Linux distributions (e.g., Red Hat). The attack requires local access on the same physical core as the victim process...

CVE-2018-16868

A Bleichenbacher type side-channel based padding oracle attack was found in the way gnutls handles verification of RSA decrypted PKCS1 v1.5 data. An attacker who is able to run process on the same physical core as the victim process, could use this to extract plaintext or in some cases downgrade...

CVE-2018-16869

CVE-2018-16869 is a Bleichenbacher-type side-channel padding oracle vulnerability in the nettle cryptographic library, caused by how nettle handles endian conversion of RSA-decrypted PKCS#1 v1.5 data. Exploitation could allow an attacker on the same physical core to extract plaintext or, in some ...
