Vulnerability Details
=====================

Class:       Information Leak
Affected:    3.3.2 to 3.4.3, 3.5 to 3.5.1
Fixed In:    3.4.4, 3.5.2
Description: When a bug is in a group, none of its information
             (other than its status and resolution) should be visible
             to users outside that group. It was discovered that
             as of 3.3.2, Bugzilla was showing the alias of the bug 
             (a very short string used as a shortcut for looking up
             the bug) to users outside of the group, if the protected
             bug ended up in the "Depends On" or "Blocks" list of any
             other bug.
