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

">=mail-filter/opendkim-2.10.3-r8"
