Description

Miroslav Lichvar discovered that Newt incorrectly handled rendering in a text box. An attacker could exploit this and cause a denial of service or possibly execute arbitrary code with the privileges of the user invoking the program.

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.
