Synopsis
=======
A vulnerability in OptiPNG might result in user-assisted execution of
arbitrary code.

Background
=========
OptiPNG is a PNG optimizer that recompresses image files to a smaller
size, without losing any information.

Affected packages
================
    -------------------------------------------------------------------
     Package            /  Vulnerable  /                    Unaffected
    -------------------------------------------------------------------
  1  media-gfx/optipng       < 0.6.2                          >= 0.6.2

Description
==========
A buffer overflow in the BMP reader in OptiPNG has been reported.

Impact
=====
A remote attacker could entice a user to process a specially crafted
BMP image, possibly resulting in the execution of arbitrary code with
the privileges of the user running the application, or a Denial of
Service.

Workaround
=========
There is no known workaround at this time.

Resolution
=========
All OptiPNG users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=media-gfx/optipng-0.6.2"
