Details

It was discovered that GD incorrectly handled memory when processing
certain images. A remote attacker could use this issue with a specially
crafted image file to cause GD to crash, resulting in a denial of service,
or possibly execute arbitrary code.

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

Ubuntu 18.10

In general, a standard system update will make all the necessary changes.
