Description

The remote Ubuntu 14.04 LTS / 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3555-1 advisory.

 It was discovered that w3m incorrectly handled certain inputs. An attacker could possibly use this to cause a denial of service. (CVE-2018-6196, CVE-2018-6197)
