Hi,

Using last CVS version of RKhunter, there is an error on the check of unhide results.

Following is an extract of rkhunter.log :

   [13:03:54] Info: Starting test name 'hidden_procs'
   [13:03:54] Info: Found the 'unhide-linux' command: /root/unhide/unhide-linux
   [13:03:54] Info: Found 'unhide' command version: 20130526
   [13:03:58]     Using command '/root/unhide/unhide-linux  -m quick' [ None
   found ]
   [13:03:58]     Using command '/root/unhide/unhide-linux  -m reverse' [ None
   found ]
   [13:04:13]     Using command '/root/unhide/unhide-linux  -m procall' [ None
   found ]
   [13:04:21]     Using command '/root/unhide/unhide-linux  -m brute' [ None
   found ]
   [13:04:21]   Checking for hidden processes                   [ Warning ]
   [13:04:21]

I test with with version 1.4.0 of RKhunter, the problem did already exist.

If I disable all tests but hidden_procs the check is OK :

   [14:25:51] Info: Starting test name 'hidden_procs'
   [14:25:51] Info: Found the 'unhide-linux' command: /root/unhide/unhide-linux
   [14:25:51] Info: Found 'unhide' command version: 20130526
   [14:25:55]     Using command '/root/unhide/unhide-linux  -m quick' [ None
   found ]
   [14:25:55]     Using command '/root/unhide/unhide-linux  -m reverse' [ None
   found ]
   [14:26:11]     Using command '/root/unhide/unhide-linux  -m procall' [ None
   found ]
   [14:26:20]     Using command '/root/unhide/unhide-linux  -m brute' [ None
   found ]
   [14:26:20]   Checking for hidden processes                   [ None found ]
   [14:26:20]

The problem comes from line 13918 :

        elif [ -z "${HIDDEN_PROCS}" -a $ERRCODE -ne 1 -a $SEEN -eq 1 ]; then

ERRCODE is not set by the hidden_procs test. When running all tests :

          ENABLE_TESTS=ALL
          DISABLE_TESTS=suspscan deleted_files packet_cap_apps apps

the value of ERRCODE is '1' from a previous test. I echoed the value just before their test :

FOUND :  1 HIDDEN_PROCS : ""  ERRCODE :  1  SEEN :  1

Regards.
