DESCRIPTION:
Some security issues have been reported in MasqMail, which can be
exploited by malicious, local users to perform certain actions with
escalated privileges.

1) Logic errors when changing the effective user and group IDs can
lead to the application running with higher privileges than intended,
which can be exploited to perform certain actions with escalated
privileges.

2) The application does not properly verify the return value when
changing privileges, which can be exploited to perform certain
actions with escalated privileges.

The security issues have been reported in version 0.2.29. Other
versions may also be affected.

SOLUTION:
Restrict access to trusted users only.
