Background =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D 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 =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 mail-filter/opendkim < 2.10.3-r8 >=3D 2.10.3-r8=20 Description =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D It was discovered that Gentoo=E2=80=99s OpenDKIM ebuild does not properly s= et permissions or place the pid file in a safe directory. Impact =3D=3D=3D=3D=3D=3D A local attacker could escalate privileges. Workaround =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D Users should ensure the proper permissions are set as discussed in the referenced bugs. Resolution =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D All OpenDKIM users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=3Dmail-filter/opendkim-2.10.3-r8" References =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D Availability =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D This GLSA and any updates to it are available for viewing at the Gentoo Security Website: https://security.gentoo.org/glsa/201904-22 Concerns? =3D=3D=3D=3D=3D=3D=3D=3D=3D Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users' machines is of utmost importance to us.
