Synopsis
========

A buffer overflow in GNU Chess might allow arbitrary code execution.

Background
==========

GNU Chess is a console based chess interfae.

Affected packages
=================

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  games-board/gnuchess        < 6.2.8-r1               >= 6.2.8-r1

Description
===========

The cmd_pgnload() and cmd_pgnreplay() functions in cmd.cc in GNU Chess
to not sufficiently validate PGN file input, potentially resulting in a
buffer overflow.

Impact
======

A remote attacker could entice a user to open a specially crafted PGN
file using GNU Chess, 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 GNU Chess users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=games-board/gnuchess-6.2.8-r1"
