acpid is a daemon that dispatches ACPI events to user-space programs. Anthony de Almeida Lopes of Outpost24 AB reported a denial of service flaw in the acpid daemon"s error handling. If an attacker could exhaust the sockets open to acpid, the daemon would enter an infinite loop, consuming most CPU resources and preventing acpid from communicating with legitimate processes. Users are advised to upgrade to this updated package, which contains a backported patch to correct this issue.
