Synopsis
=======
zgv contains multiple buffer overflows that can potentially lead to the
execution of arbitrary code.

Background
=========
zgv is a console image viewer based on svgalib.

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

  1  media-gfx/zgv        < 5.8                                 >= 5.8

Description
==========
Multiple arithmetic overflows have been detected in the image
processing code of zgv.

Impact
=====
An attacker could entice a user to open a specially-crafted image file,
potentially resulting in execution of arbitrary code with the rights of
the user running zgv.

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

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

    # emerge --sync
