Synopsis
========

A vulnerability was discovered in Gentoo's ebuild for OpenDKIM which
could lead to root privilege escalation.

Background
==========

A community effort to develop and maintain a C library for producing
DKIM-aware applications and an open source milter for providing DKIM
service.

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

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  mail-filter/opendkim       < 2.10.3-r8              >= 2.10.3-r8 

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

It was discovered that Gentoo’s OpenDKIM ebuild does not properly set
permissions or place the pid file in a safe directory.

Impact
======

A local attacker could escalate privileges.

Workaround
==========

Users should ensure the proper permissions are set as discussed in the
referenced bugs.

Resolution
==========

All OpenDKIM users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=mail-filter/opendkim-2.10.3-r8"

References
==========
