DESCRIPTION:
A security issue has been reported in acpid, which can be exploited
by malicious, local users to cause a DoS (Denial of Service).

The security issue is caused due to the daemon using a socket in
blocking mode to communicate with unprivileged programs, which can be
exploited to cause the daemon to hang.

The security issue is reported in version 1.0.10. Other versions may
also be affected.

SOLUTION:
Restrict access to trusted users only.
