    Vulnerability  : privilege escalation

    Debian-specific: no
    
    The developers of Bugzilla, a web-based bug tracking system,
    discovered a problem in the handling of more than 47 groups.  When a
    new product is added to an installation with 47 groups or more and
    "usebuggroups" is enabled, the new group will be assigned a groupset
    bit using Perl math that is not exact beyond 2^48.  This results in
    the new group being defined with a "bit" that has several bits set.
    As users are given access to the new group, those users will also gain
    access to spurious lower group privileges.  Also, group bits were not
    always reused when groups were deleted.
    
    This problem has been fixed in version 2.14.2-0woody2 for the current
    stable distribution (woody) and will soon be fixed in the unstable
    distribution (sid).  The old stable distribution (potato) doesn't
    contain a bugzilla package.
    
    We recommend that you upgrade your bugzilla package.
    
    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.
