    Since the initial posting on Dec 5, we have been collaborating closely with the author to
    better understand the issues raised and we are wotking with him to provide a timely 
    solution.  Our product teams are working on patches.
    
    The issues can be broken down into three areas:
    
    o Permission setting on LSF error log
    
       If you are using the default LSF 4.2 installation, you would not have any exposure 
       because the LSF error log directory can only be written by root or the LSF
       administrator.
    
       If you are using syslog or if error log is in a directory that is writeable only by root, you
       would not be exposed.
    
       You can check the permission of your LSF error log directory (LSF_LOGDIR
       parameter in the lsf.conf) to make sure it is not writable by regular users.
    
    o setuid binaries
    
       In an LSF installation configured with Kerberos, there are only two setuid binaries, 
       lsadmin and badmin, which are administrator commands.  You can unset the setuid
       bits for these two binaries, and run these commands as root to perform administration
       operation.
    
       A patch will address the setuid issues raised in the posting.
    
    o Buffer overflows
    
      We are doing a thorough investigation into all sources of buffer overflows.
    
    
    Updates to our progress will be posted when available.
    
    take care,
    
    Greg
