USN-5078-1 fixed a vulnerability in Squashfs-Tools. That update was incomplete and could still result in Squashfs-Tools mishandling certain malformed SQUASHFS files. This update fixes the problem.

We apologize for the inconvenience.

Original advisory details:

Richard Weinberger discovered that Squashfs-Tools mishandled certain malformed SQUASHFS files. An attacker could use this vulnerability to write arbitrary files to the filesystem.
