NVD Description

Note: Versions mentioned in the description apply only to the upstream gnutls-dane package and not the gnutls-dane package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

A Bleichenbacher type side-channel based padding oracle attack was found in the way gnutls handles verification of RSA decrypted PKCS#1 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 any TLS connections to a vulnerable server.
