Updated bugzilla packages fix security vulnerabilities:
If a new comment was marked private to the insider group, and a flag was set in the same transaction, the comment would be visible to flag recipients even if they were not in the insider group (CVE-2014-1571).
An attacker creating a new Bugzilla account can override certain parameters when finalizing the account creation that can lead to the user being created with a different email address than originally requested. The overridden login name could be automatically added to groups based on the group's regular expression setting (CVE-2014-1572).
During an audit of the Bugzilla code base, several places were found where cross-site scripting exploits could occur which could allow an attacker to access sensitive information (CVE-2014-1573).
