DESCRIPTION:
Gotfault Security has discovered a vulnerability in Power Daemon
(powerd), which can be exploited by malicious people to cause a DoS
(Denial of Service) and potentially compromise a vulnerable system.

The vulnerability is caused due to a format string error in powerd.c
when logging input received via the "WHATIDO" command. This can be
exploited to crash powerd and may allow arbitrary code execution.

Successful exploitation requires that powerd is configured to send
notification messages to a malicious host.

The vulnerability has been confirmed in version 2.0.2. Other versions
may also be affected.

SOLUTION:
Send notification messages to trusted hosts only.
