Postfix: Privilege escalation

Postfix: Privilege escalation A vulnerability in Postfix may allow local users to gain root privileges. postfix 2017-09-24 2017-09-24 621882 local 3.1.6 3.1.6

Postfix is a mail server and an alternative to the widely-used Sendmail program.

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"
