Ubuntu 14.04 LTS / 16.04 LTS / 18.04 LTS / 18.10 : libgd2 vulnerabilities (USN-3900-1)

High Nessus Plugin ID 122533

Synopsis

The remote Ubuntu host is missing one or more security-related patches.

Description

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.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected libgd-tools and / or libgd3 packages.
