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
    -------------------------------------------------------------------
  1  media-gfx/openscad          < 2021.01                 >= 2021.01 

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
==========

There is no known workaround at this time.

Resolution
==========

All OpenSCAD users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=media-gfx/openscad-2021.01"
