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.

The remote Redhat Enterprise Linux 5 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - 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)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

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.
