The daemon in acpid before 1.0.10 allows remote attackers to cause a denial of service (CPU consumption and connectivity loss) by opening a large number of UNIX sockets without closing them, which triggers an infinite loop (CVE-2009-0798). The updated packages have been patched to prevent this. Affected: 2008.1, 2009.0, 2009.1, Corporate 3.0, Corporate 4.0, Multi Network Firewall 2.0
