Title: Postfix: Privilege escalation (GLSA 201709-20)
A vulnerability in Postfix may allow local users to gain root
Postfix is a mail server and an alternative to the widely-used Sendmail
Vulnerable: < 3.1.6
Unaffected: >= 3.1.6
Architectures: All supported architectures
By default, Berkeley DB reads a DB_CONFIG configuration file from the
current working directory. This is an undocumented behavior.
A local attacker, by using a specially crafted DG_CONFIG file, could
possibly escalate privileges to the root group.
There is no known workaround at this time.
All Postfix users should upgrade to the latest version:
|# emerge --sync
# emerge --ask --oneshot --verbose ">=mail-mta/postfix-3.1.6"
