Synopsis
========

zip contains a buffer overflow when creating a ZIP archive of files
with very long path names. This could lead to the execution of
arbitrary code.

Background
==========

zip is a compression and file packaging utility.

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

    -------------------------------------------------------------------
     Package       /  Vulnerable  /                         Unaffected
    -------------------------------------------------------------------
  1  app-arch/zip      <= 2.3-r3                             >= 2.3-r4

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

zip does not check the resulting path length when doing recursive
folder compression.

Impact
======

An attacker could exploit this by enticing another user or web
application to create an archive including a specially-crafted path
name, potentially resulting in the execution of arbitrary code with the
permissions of the user running zip.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All zip users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=app-arch/zip-2.3-r4"
