==========================================================================

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

- Ubuntu 17.04
- Ubuntu 16.10
- Ubuntu 16.04 LTS
- Ubuntu 14.04 LTS

Summary:

libmwaw could be made to crash or run programs as your login if it opened a
specially crafted file.

Software Description:
- libmwaw: import library for some old Mac text documents

Details:

It was discovered that libmwaw incorrectly handled certain malformed
document files. If a user or automated system were tricked into opening a
specially crafted file, a remote attacker could cause libmwaw to crash,
resulting in a denial of service, or possibly execute arbitrary code.

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

Ubuntu 17.04:
  libmwaw-0.3-3                   0.3.9-1ubuntu0.1
