CVE-2019-2692

Description

From CVE.org

Vulnerability in the MySQL Connectors component of Oracle MySQL (subcomponent: Connector/J). Supported versions that are affected are 8.0.15 and prior. Difficult to exploit vulnerability allows high privileged attacker with logon to the infrastructure where MySQL Connectors executes to compromise MySQL Connectors. Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in takeover of MySQL Connectors. CVSS 3.0 Base Score 6.3 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.0/AV:L/AC:H/PR:H/UI:R/S:U/C:H/I:H/A:H).

Statement

Red Hat Satellite does not support using mysql as a back end database, thus the mysql connector is not used in any Satellite installation.

The package mariadb Java client is now available in Red Hat Software Collections. It can be installed this way:

   yum-config-manager --enable rhel-server-rhscl-7-rpms
   yum install rh-mariadb103-mariadb-java-client

This JDBC driver works fine with both, MariaDB and MySQL servers. We recommend use of mariadb-java-client over mysql-java-connector where possible.

Common Vulnerability Scoring System (CVSS) Score Details

Info alert:Important note

CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).

Understanding the Weakness (CWE)

Availability,Integrity,Confidentiality

Technical Impact: Read Memory; Modify Memory; Execute Unauthorized Code or Commands; DoS: Crash, Exit, or Restart

When a memory buffer is accessed using the wrong type, it could read or write memory out of the bounds of the buffer, if the allocated buffer is smaller than the type that the code is attempting to access, leading to a crash and possibly code execution.
