GLSA-201709-20 : Postfix: Privilege escalation
High Nessus Plugin ID 103448
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe 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.
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.
SolutionAll Postfix users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=mail-mta/postfix-3.1.6'
