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

Description

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

Impact

Workaround
=========
Users should ensure the proper permissions are set as discussed in the
