  acpid                           1.0.4-1ubuntu11.2

Ubuntu 8.04 LTS:
  acpid                           1.0.4-5ubuntu9.3

Ubuntu 8.10:
  acpid                           1.0.6-9ubuntu4.8.10.2

Ubuntu 9.04:
  acpid                           1.0.6-9ubuntu4.9.04.2

It was discovered that acpid did not properly handle a large number of
connections. A local user could exploit this and monopolize CPU resources,
leading to a denial of service.
