Synopsis
=======
A buffer overflow in OpenSCAD might allow remote attacker(s) to execute
arbitrary code.

Background
=========
OpenSCAD is the programmer's solid 3D CAD modeller.

Affected packages
================
    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected

Description
==========
A buffer overflow exists in OpenSCAD when parsing STL files.

Impact
=====
A remote attacker could entice a user to open a specially crafted STL
file using OpenSCAD, possibly resulting in execution of arbitrary code
with the privileges of the process or a Denial of Service condition.

Workaround
