Two vulnerabilities have been reported in Bugzilla, which can be exploited by malicious users to conduct spoofing attacks and by malicious people to conduct cross-site request forgery attacks.
1) An error within the handling of email addresses containing certain UTF-8 encoded characters can be exploited to e.g. impersonate another user.
2) The application allows users to perform certain actions via HTTP requests without performing proper validity checks to verify the requests. This can be exploited to e.g. change certain bug data or execute certain administrative tasks when a logged-in user visits a specially crafted web page.
Please see the vendor's advisory for a list of affected versions.
Solution: Update to version 3.4.14, 3.6.8, or 4.0.4.
Provided and/or discovered by: 1) James Kettle within a bug report.
2) Mario Gomes within a bug report.
