critical Nessus Plugin ID 183561

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 16.04 ESM host has packages installed that are affected by a vulnerability as referenced in the USN-5438-2 advisory.

 USN-5438-1 fixed a vulnerability in HTMLDOC. This update provides the corresponding update for Ubuntu 14.04 ESM and Ubuntu 16.04 ESM.

 Original advisory details:

 It was discovered that HTMLDOC did not properly manage memory under certain

 circumstances. If a user were tricked into opening a specially crafted HTML

 file, a remote attacker could possibly use this issue to cause HTMLDOC to

 crash, resulting in a denial of service, or possibly execute arbitrary code.

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

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution
