USN-501-1 fixed vulnerabilities in Jasper. This update provides the corresponding update for the Jasper internal to Ghostscript.

It was discovered that Jasper did not correctly handle corrupted JPEG2000 images. By tricking a user into opening a specially crafted JPG, a remote attacker could cause the application using libjasper to crash, resulting in a denial of service.

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.
