A community effort to develop and maintain a C library for producing DKIM-aware applications and an open source milter for providing DKIM service.
It was discovered that Gentoo’s OpenDKIM ebuild does not properly set permissions or place the pid file in a safe directory.
A local attacker could escalate privileges.
Users should ensure the proper permissions are set as discussed in the referenced bugs.
All OpenDKIM users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=mail-filter/opendkim-2.10.3-r8"
