the USN-3214-1 advisory.

    A large number of security issues were discovered in the w3m browser. If a user were tricked into viewing
    a malicious website, a remote attacker could exploit a variety of issues related to web browser security,
    including cross-site scripting attacks, denial of service attacks, and arbitrary code execution.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
