Bugzilla is a Web-based bug-tracking system used by a large number of
software projects. The following security issues have been discovered
* When a user creates a new account, Bugzilla doesn't correctly
reject email addresses containing non-ASCII characters, which
could be used to impersonate another user account.
* A CSRF vulnerability in the implementation of the JSON-RPC API
could be used to make changes to bugs or execute some admin tasks
without the victim's knowledge.
All affected installations are encouraged to upgrade as soon as
Class: Account Impersonation
Versions: 2.0 to 3.4.13, 3.5.1 to 3.6.7, 3.7.1 to 4.0.3,
4.1.1 to 4.2rc1
Fixed In: 3.4.14, 3.6.8, 4.0.4, 4.2rc2
Description: When a user creates a new account, Bugzilla doesn't
correctly reject email addresses containing non-ASCII
characters, which could be used to impersonate another
user account. Such email addresses could look visually
identical to other valid email addresses, and an attacker
could try to confuse other users and be added to bugs he
shouldn't have access to.
CVE Number: CVE-2012-0448
Class: Cross-Site Request Forgery
Versions: 3.5.1 to 3.6.7, 3.7.1 to 4.0.3, 4.1.1 to 4.2rc1
Fixed In: 3.6.8, 4.0.4, 4.2rc2
Description: Due to a lack of validation of the Content-Type header
when making POST requests to jsonrpc.cgi, a possible
CSRF vulnerability was discovered. If a user visits an
HTML page with some malicious JS code in it, an attacker
could make changes to a remote Bugzilla installation on
behalf of the victim's account by using the JSON-RPC API.
The user would have had to be already logged in to the
target site for the vulnerability to work.
CVE Number: CVE-2012-0440
