DSA-173-1 bugzilla -- privilege escalation

In Mitre's CVE dictionary: CVE-2002-1196.
More information:

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 248. 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.

Fixed in:

Debian GNU/Linux 3.0 (woody)
