"Oliver-Tobias Ripka discovered that an ACPI script incorrectly handled
power button events. A local attacker could use this to execute
arbitrary code, and possibly escalate privileges. (CVE-2011-2777)

Helmut Grohne and Michael Biebl discovered that ACPI scripts were
executed with a permissive file mode creation mask (umask). A local
attacker could read files and modify directories created by ACPI
scripts that did not set a strict umask. (CVE-2011-4578).

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
