USN-4603-1: MariaDB vulnerabilities

27 October 2020

Several security issues were fixed in MariaDB.




It was discovered that MariaDB didn't properly validate the content of a packet
received from a server. A remote attacker could use this vulnerability to sent
a specialy crafted file to cause a denial of service. (CVE-2020-13249)

It was discovered that MariaDB has other security issues. An attacker can cause
a hang or frequently repeatable crash (denial of service). (CVE-2020-15180,
CVE-2020-2752, CVE-2020-2760, CVE-2020-2812, CVE-2020-2814)

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

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 20.04
Ubuntu 18.04

This update uses a new upstream release, which includes additional bug
fixes. After a standard system update you need to restart MariaDB to
make all the necessary changes.
