Description filip ambroz 2020-02-02 00:15:56 UTC
smtp_mailaddr in smtp_session.c in OpenSMTPD 6.6, as used in OpenBSD 6.6 and other products, allows remote attackers to execute arbitrary commands as root via a crafted SMTP session, as demonstrated by shell metacharacters in a MAIL FROM field. This affects the "uncommented" default configuration. The issue exists because of an incorrect return value upon failure of input validation.
Comment 1 filip ambroz 2020-02-02 00:23:30 UTC
Versions prior to 6.6 also vulnerable?
