An issue was discovered in the Tatsuya Kinoshita w3m fork before 0.5.3-31. w3m allows remote attackers to cause a denial of service (out-of-bounds array access) via a crafted HTML page.

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

  - Integer overflow vulnerability in bdwgc before 2016-09-27 allows attackers to cause client of bdwgc denial
    of service (heap buffer overflow crash) and possibly execute arbitrary code via huge allocation.
    (CVE-2016-9427)

  - An issue was discovered in the Tatsuya Kinoshita w3m fork before 0.5.3-31. The feed_table_tag function in
    w3m doesn't properly validate the value of table span, which allows remote attackers to cause a denial of
    service (stack and/or heap buffer overflow) and possibly execute arbitrary code via a crafted HTML page.
    (CVE-2016-9422)

  - An issue was discovered in the Tatsuya Kinoshita w3m fork before 0.5.3-31. Heap-based buffer overflow in
    w3m allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a
    crafted HTML page. (CVE-2016-9423)

  - An issue was discovered in the Tatsuya Kinoshita w3m fork before 0.5.3-31. w3m doesn't properly validate
    the value of tag attribute, which allows remote attackers to cause a denial of service (heap buffer
    overflow crash) and possibly execute arbitrary code via a crafted HTML page. (CVE-2016-9424)

  - An issue was discovered in the Tatsuya Kinoshita w3m fork before 0.5.3-31. Heap-based buffer overflow in
    the addMultirowsForm function in w3m allows remote attackers to cause a denial of service (crash) and
    possibly execute arbitrary code via a crafted HTML page. (CVE-2016-9425)

The remote Ubuntu 14.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in 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 number.

The remote host is affected by the vulnerability described in GLSA-201701-08 (w3m: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in w3m. Please review the       CVE identifiers referenced below for details.
  Impact :

    A remote attacker could execute arbitrary code with the privileges of       the process or cause a Denial of Service condition via a maliciously       crafted HTML file.
  Workaround :

    There is no known workaround at this time.

Multiple remote code execution and denial of service conditions present.
