FreeBSD : mysql -- ALTER MERGE denial of service vulnerability (06a6b2cf-484b-11d9-813c-00065be4b5b6)

Low Nessus Plugin ID 18830


The remote FreeBSD host is missing one or more security-related updates.


Dean Ellis reported a denial of service vulnerability in the MySQL server :

Multiple threads ALTERing the same (or different) MERGE tables to change the UNION eventually crash the server or hang the individual threads.

Note that a script demonstrating the problem is included in the MySQL bug report. Attackers that have control of a MySQL account can easily use a modified version of that script during an attack.


Update the affected packages.
