    Package        : perl
    Vulnerability  : information leak
    Problem-Type   : local
    Debian-specific: no
    CVE Ids        : CAN-2003-0618
    
    Paul Szabo discovered a number of similar bugs in suidperl, a helper
    program to run perl scripts with setuid privileges.  By exploiting
    these bugs, an attacker could abuse suidperl to discover information
    about files (such as testing for their existence and some of their
    permissions) that should not be accessible to unprivileged users.
    
    For the current stable distribution (woody) this problem has been
    fixed in version 5.6.1-8.6.
    
    For the unstable distribution, this problem will be fixed soon.  Refer
    to Debian bug #220486.
    
    We recommend that you update your perl package if you have the
    "perl-suid" package installed.
    
    Upgrade Instructions
    - --------------------
    
    wget url
            will fetch the file for you
    dpkg -i file.deb
            will install the referenced file.
    
    If you are using the apt-get package manager, use the line for
    sources.list as given below:
    
    apt-get update
            will update the internal database
    apt-get upgrade
            will install corrected packages
    
    You may use an automated update by adding the resources from the
    footer to the proper configuration.
