Fedora 30: FEDORA-2020-31216ab928 Critical: OpenSMTPD Command Injection

OpenSMTPD is a FREE implementation of the server-side SMTP protocol as defined

by RFC 5321, with some additional standard extensions. It allows ordinary

machines to exchange e-mails with other systems speaking the SMTP protocol.

Started out of dissatisfaction with other implementations, OpenSMTPD nowadays

is a fairly complete SMTP implementation. OpenSMTPD is primarily developed

by Gilles Chehade, Eric Faurot and Charles Longeau; with contributions from

various OpenBSD hackers. OpenSMTPD is part of the OpenBSD Project.

The software is freely usable and re-usable by everyone under an ISC license.

This package uses standard "alternatives" mechanism, you may call

"/usr/sbin/alternatives --set mta /usr/sbin/sendmail.opensmtpd"

if you want to switch to OpenSMTPD MTA immediately after install, and

"/usr/sbin/alternatives --set mta /usr/sbin/sendmail.sendmail" to revert

back to Sendmail as a default mail daemon.

Release 6.6.4p1 (2020-02-24) --- - An out of bounds read in smtpd allows an

attacker to inject arbitrary commands into the envelope file which are then

executed as root. Separately, missing privilege revocation in smtpctl allows

arbitrary commands to be run with the _smtpq group. Release 6.6.3p1

(2020-02-10) --- - Following the 6.6.2p1 release, various improvements were

done in OpenBSD -current to mitigate the risk of similar bugs.
