Synopsis
========

A vulnerability in Coreutils could lead to the execution of arbitrary
code or a Denial of Service condition.

Background
==========

The GNU Core Utilities are the basic file, shell and text manipulation
utilities of the GNU operating system.

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

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected

  1  sys-apps/coreutils            < 8.23                     >= 8.23

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

A memory corruption flaw in GNU Coreutils' parse_datetime function was
reported. Applications using parse_datetime(), such as touch or date,
may accepted untrusted input.

Impact

A remote attacker could possibly execute arbitrary code with the
privileges of the process, or cause a Denial of Service condition.

Workaround
==========

There is no known workaround at this time.

Resolution

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=sys-apps/coreutils-8.23"
