MySQL < 3.23.55 Double Free() Overflow

high Log Correlation Engine Plugin ID 801161
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


The remote host is vulnerable to a buffer overflow.


The remote host is running a version of MySQL which is older than version 3.23.55. If you have not patched this version, then any attacker with a valid username may crash this service remotely by exploiting a double free bug.
Further exploitation to gain a shell on the host may also be possible.


Upgrade to MySQL 3.23.55 or higher.
