Description

It was discovered that GTK+ incorrectly handled certain large images. A remote attacker could use this issue to cause GTK+ applications 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.
