"The remote host is running the apcupsd client which, according to its
version number, is affected by multiple vulnerabilities :

  - The configuration file '/var/run/apcupsd.pid' is by
    default world-writable. A local attacker could re-write 
    this file with other process IDs in order to crash the
    affected system.

  - An issue exists in the 'log_event' function which a
    local attacker could exploit in order to execute
    arbitrary code.

  - Several buffer overflow vulnerabilities have been
    reported which a remote attacker could exploit in order
    to execute arbitrary code on the remote host.

*** Nessus solely relied on the version number of the 
*** remote server, so this might be a false positive" );
