apcupsd for APC UPS systems contains a flaw that may allow a local denial of service. The problem is that the daemon saves its process ID in a world-writable file, which could allow a malicious user to overwrite the 'apcups.pid' file with an arbitrary process ID to cause the system to crash during restart or shutdown, resulting in a loss of availability for the system.
