CVE-2011-4578 (
  event.c in acpid (aka acpid2) before 2.0.11 does not have an appropriate
  umask setting during execution of event-handler scripts, which might allow
  local users to (1) perform write operations within directories created by a
  script, or (2) read files created by a script, via standard filesystem
  system calls.
