    There exists a security / DOS problem with linuxconf-1.11.r11-rh3/i386
    as upgraded from RedHat's FTP site.  No other versions have been tested
    by me.  Both the maintainer of linuxconf and RedHat Software were made
    aware of this problem.
    
    [root@machine SRPMS]# rpm -q linuxconf
    linuxconf-1.11r11-rh3
    
    The details of the problem are neither new nor exciting so a very brief
    description follows:
    
    linuxconf creates at least one file in /tmp during/at execution, and
    will blindly follow a symlink from that file.  As linuxconf is an admin
    tool, and can/should only be run as root, the possibilities of system
    smashing are multiple.
    
    A version of linuxconf that does not have this problem is available at:
    ftp://ftp.solucorp.qc.ca/pub/linuxconf/devel/redhat-5.1/linuxconf-1.11r19-1.i386.rpm
    
    Thanks to Jacques Gelinas (linuxconf maintainer)  for releasing a fixed
    version quickly.
