CVE-ID : CVE-2020-7247
Package : opensmtpd
Type : arbitrary command execution
Remote : Yes
Link : https://security.archlinux.org/AVG-1090
The package opensmtpd before version 6.6.2p1-1 is vulnerable to
arbitrary command execution.
Upgrade to 6.6.2p1-1.
The problem has been fixed upstream in version 6.6.2p1.
None.
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.
A remote attacker is able to execute arbitrary commands as root on the
affected host.
