high Nessus Plugin ID 103448

Language:

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-201709-20 (Postfix: Privilege escalation)

 By default, Berkeley DB reads a DB_CONFIG configuration file from the current working directory. This is an undocumented behavior.
 Impact :

 A local attacker, by using a specially crafted DG_CONFIG file, could possibly escalate privileges to the root group.
 Workaround :

 There is no known workaround at this time.

Solution

All Postfix users should upgrade to the latest version:
 # emerge --sync # emerge --ask --oneshot --verbose '>=mail-mta/postfix-3.1.6'
