newt is vulnerable to arbitrary code execution. The vulnerability exists as a heap-based buffer overflow flaw was found in the way newt processes content that is to be displayed in a text dialog box. A local attacker could issue a specially-crafted text dialog box display request (direct or via a custom application), leading to a denial of service (application crash) or, potentially, arbitrary code execution with the privileges of the user running the application using the newt library.
