Synopsis
========

A heap-based buffer overflow in cpio might allow a remote rmt server to
execute arbitrary code or cause a Denial of Service condition.

Background
==========

GNU cpio copies files into or out of a cpio or tar archive.

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

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  app-arch/cpio                 < 2.11                     >= 2.11

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

Cpio contains a heap-based buffer overflow in the rmt_read__ function
in lib/rtapelib.c.

Impact
======

A remote server could sending more data than was requested, related to
archive filenames that contain a : (colon) character, possibly
resulting in execution of arbitrary code or a Denial of Service
condition.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All cpio users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=app-arch/cpio-2.11"
