Vulnerability in the MySQL Server component of Oracle MySQL (subcomponent: Server: Optimizer). Supported versions that are affected are 5.7.26 and prior and 8.0.16 and prior. Easily exploitable vulnerability allows high privileged attacker with network access via multiple protocols to compromise MySQL Server. Successful attacks of this vulnerability can result in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of MySQL Server. CVSS 3.0 Base Score 4.9 (Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H).

**MySQL 8.0.17**

This update brings the latest MySQL 8.0.17 which fixes severe security issues. Now available as both a standard package and a module!

Release notes :

https://dev.mysql.com/doc/relnotes/mysql/8.0/en/news-8-0-17.html

Mainatiner notes :

  - The MySQL Modules are now built from the same sources as     the base packages, so the should be identical

  - The package is now being built with number of standard     Fedora build flags that has not been used before. The     package should be now more stable and secure.

  - In Modules, the bug #1729133 still exists

  - The MySQL 5.7 and 5.6 Modules may exists, but I'm out of     capacity to maintain them. Whenever possible upgrade to     MySQL 8.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora update system website.
Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

An update for the mysql:8.0 module is now available for Red Hat Enterprise Linux 8.

Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

MySQL is a multi-user, multi-threaded SQL database server. It consists of the MySQL server daemon, mysqld, and many client programs.

Multiple security issues were discovered in MySQL and this update includes a new upstream MySQL version to fix these issues.

Ubuntu 16.04 LTS, Ubuntu 18.04 LTS, and Ubuntu 19.04 have been updated to MySQL 5.7.27.

In addition to security fixes, the updated packages contain bug fixes, new features, and possibly incompatible changes.

Please see the following for more information:

Oracle reports :

This Critical Patch Update contains 45 new security fixes for Oracle MySQL. 4 of these vulnerabilities may be remotely exploitable without authentication, i.e., may be exploited over a network without requiring user credentials.

The version of MySQL running on the remote host is 8.0.x prior to 8.0.17. It is, therefore, affected by multiple vulnerabilities, including three of the top vulnerabilities below, as noted in the July 2019 and October 2022 Critical Patch Update advisories:

  - An unspecified vulnerability in the     'Shell: Admin / InnoDB Cluster' subcomponent could allow     an unauthenticated attacker to takeover an affected MySQL     Server. A successful attack requires user interaction.
    (CVE-2019-2822)

  - As unspecified vulnerability in the 'Server: Replication'     subcomponent could allow an unauthenticated attacker to     cause the server to hang or to, via a frequently     repeatable crash, cause a complete denial of service.
    Additionally, a successful attacker could perform     unauthorized modifications to some MySQL Server     accessible data. (CVE-2019-2800)

  - As unspecified vulnerability in the 'Server: Charsets'     subcomponent could allow an unauthenticated attacker to     cause the server to hang or to, via a frequently     repeatable crash, cause a complete denial of service.
    (CVE-2019-2795)

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

The version of MySQL running on the remote host is 5.7.x prior to 5.7.27. It is, therefore, affected by multiple vulnerabilities, including three of the top vulnerabilities below, as noted in the July 2019 Critical Patch Update advisory:

  - A stack-based buffer overflow vulnerability in the     'Server: Packaging (cURL)' subcomponent could allow an     unauthenticated attacker to gain complete control of an     affected instance of MySQL Server. (CVE-2019-3822)

  - A vulnerability in the 'Server: Parser' subcomponent.
    This is an easily exploitable vulnerability that allows     a low privileged attacker with network access via     multiple protocols to compromise the server. Successful     attacks involving this vulnerability can result in the     unauthorized ability to cause a hang or frequently     repeatable crash (complete DOS). (CVE-2019-2805)

  - A vulnerability in the 'Server: XML' subcomponent. This     is an easily exploitable vulnerability that allows a     low privileged attacker with network access via multiple     protocols to compromise a server.Successful attacks     involving this vulnerability can result in the     unauthorized ability to cause a hang or frequently     repeatable crash (complete DOS).
