DESCRIPTION:
Some vulnerabilities have been reported in Bugzilla, which can be
exploited by malicious users to conduct script insertion attacks and
by malicious people to conduct HTTP response splitting attacks,
cross-site request forgery attacks, and bypass certain security
restrictions.
 
1) An unspecified error related to insufficiently random numbers can
be exploited to gain access to a user's account.

2) Certain input is not properly sanitised before being returned to
the user. This can be exploited to insert arbitrary HTTP headers,
which will be included in a response sent to the user.

3) Certain input passed to the URL field is not properly sanitised
before being used. This can be exploited to insert HTML and script
code, which will be executed in a user's browser session in context
of an affected site if malicious data is viewed.

4) The application allows users to perform certain actions via HTTP
requests without performing proper validity checks to verify the
requests. This can be exploited when a logged-in user visits a
specially crafted web page.

SOLUTION:
Update to version 3.2.10, 3.4.10, or 3.6.4.

PROVIDED AND/OR DISCOVERED BY:
1) Willem Pinckaers, Pine Digital Security
2) Michal Zalewski, Frédéric Buclin, and Max Kanat-Alexander
4) José A. Vázquez and Reed Loden
