convert Textile markup to HTML, did not properly sanitize its input.
This allowed a remote attacker to perform a cross-site scripting
attack by injecting arbitrary JavaScript code into the generated HTML.

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