[ASA-202001-6] opensmtpd: arbitrary command execution
Arch Linux Security Advisory ASA-202001-6 ========================================= Severity: Critical Date : 2020-01-29 CVE-ID : CVE-2020-7247 Package : opensmtpd Type : arbitrary command execution Remote : Yes Link : Summary ======= The package opensmtpd before version 6.6.2p1-1 is vulnerable to arbitrary command execution. Resolution ========== Upgrade to 6.6.2p1-1. # pacman -Syu "opensmtpd>=6.6.2p1-1" The problem has been fixed upstream in version 6.6.2p1. Workaround ========== None. Description =========== 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. Impact ====== A remote attacker is able to execute arbitrary commands as root on the affected host. References ==========
