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.
