Synopsis
========

Multiple vulnerabilities have been found in 7-Zip, the worst of which
may allow execution of arbitrary code.

Background
==========

7-Zip is an open-source file archiver, an application used primarily to
compress files. 7-Zip uses its own 7z archive format, but can read and
write several other archive formats.

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

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  app-arch/p7zip              < 16.02-r1               >= 16.02-r1 

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

Multiple vulnerabilities have been discovered in 7-Zip. Please review
the CVE identifiers referenced below for details.

Impact
======

A remote attacker could entice a user to open a specially crafted
archive file 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 7-Zip users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=app-arch/p7zip-16.02-r1"
