Package        : bugzilla
Vulnerability  : privilege escalation
Problem-Type   : remote
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.

  These files will probably be moved into the stable distribution on
  its next revision.
