Detail

Synopsis

A vulnerability in Postfix may allow local users to gain root privileges.

Background

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

Description

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.

Resolution

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