October 13, 2021

squashfs-tools vulnerability
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 21.04
- Ubuntu 20.04 LTS

Summary:

Squashfs-Tools could be made to overwrite files.

Software Description:
- squashfs-tools: Tools to create and modify squashfs filesystems

Details:

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.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 21.04:
  squashfs-tools                  1:4.4-2ubuntu0.3

Ubuntu 20.04 LTS:
  squashfs-tools                  1:4.4-1ubuntu0.3

In general, a standard system update will make all the necessary changes.
