USN-3814-1 fixed several vulnerabilities in libmspack. In Ubuntu 14.04
libmspack is included into ClamAV. This update provides the
corresponding update for Ubuntu 14.04 LTS.

Original advisory details:

 It was discovered libmspack incorrectly handled certain malformed CAB files.
 A remote attacker could use this issue to cause libmspack to crash, resulting
 in a denial of service. (CVE-2018-18584, CVE-2018-18585)");
