USN-3719-1 fixed vulnerabilities in Mutt. Unfortunately, the fixes were not correctly applied to the packaging for Mutt in Ubuntu 16.04 LTS. This update corrects the oversight.

We apologize for the inconvenience.

It was discovered that Mutt incorrectly handled certain requests. An attacker could possibly use this to execute arbitrary code.
(CVE-2018-14350, CVE-2018-14352, CVE-2018-14354, CVE-2018-14359, CVE-2018-14358, CVE-2018-14353 ,CVE-2018-14357)

It was discovered that Mutt incorrectly handled certain inputs. An attacker could possibly use this to access or expose sensitive information. (CVE-2018-14355, CVE-2018-14356, CVE-2018-14351, CVE-2018-14362, CVE-2018-14349).

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.
