SynopsisThe remote Ubuntu host is missing one or more security-related patches.
DescriptionIt was discovered that libpng did not correctly handle corrupted CRC in grayscale PNG images. By tricking a user into opening a specially crafted PNG, a remote attacker could cause the application using libpng 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.
SolutionUpdate the affected libpng12-0, libpng12-dev and / or libpng3 packages.
