Oracle MySQL Connectors OpenSSL (Jan 2020 CPU)

medium Nessus Plugin ID 132937

Synopsis

The remote host is affected by multiple vulnerabilities.

Description

The version of Oracle MySQL Connectors installed on the remote host is 8.0.x prior to 8.0.19 or 5.3.x prior to 5.3.14.
It is, therefore, affected by a vulnerability in OpenSSL as noted in the January 2020 Critical Patch Update advisory.
This vulnerability is due to a susceptibility to side-channel attacks in the OpenSSL implementation which allows a local, unauthenticated attacker to fully recover a secret key during an ECDSA signature operation, provided the attacker can time the creation of a large number of signatures.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Apply the appropriate patches according to the January 2020 Oracle Critical Patch Update advisory.
