Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

Description :

The remote host is affected by the vulnerability described in GLSA-200611-04
(Bugzilla: Multiple Vulnerabilities)

The vulnerabilities identified in Bugzilla are as follows:
Frederic Buclin and Gervase Markham discovered that input passed to
various fields throughout Bugzilla were not properly sanitized before
being sent back to users (CVE-2006-5453).
Frederic Buclin and Josh 'timeless' Soref discovered a bug when
viewing attachments in diff mode that allows users not of the
'insidergroup' to read attachment descriptions. Additionally, it was
discovered that the 'deadline' field is visible to users who do not
belong to the 'timetrackinggroup' when bugs are exported to XML
(CVE-2006-5454).
Gavin Shelley reported that Bugzilla allows certain operations to
be performed via HTTP GET and HTTP POST requests without verifying
those requests properly (CVE-2006-5455).
Max Kanat-Alexander discovered that input passed to
showdependencygraph.cgi is not properly sanitized before being returned
to users (CVE-2006-5453).

Impact :

An attacker could inject scripts into the content loaded by a user's
browser in order to have those scripts executed in a user's browser in
the context of the site currently being viewed. This could include
gaining access to privileged session information for the site being
viewed. Additionally, a user could forge an HTTP request in order to
create, modify, or delete bugs within a Bugzilla instance. Lastly, an
unauthorized user could view sensitive information about bugs or bug
attachments.

Workaround :

There is no known workaround at this time.
