inputs, resulting in cross-site scripting (XSS) vulnerabilities. With
cross-site scripting vulnerabilities, if a user were tricked into
viewing server output during a crafted server request, a remote
attacker could exploit this to modify the contents, or steal
confidential data, within the same domain.

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
