Description
- A vulnerability was discovered in OpenSMTPd before version 6.6.2 which allows arbiterary code execution by constructing a mail FROM address that escapes the regex filter.
+ 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.
