Mozilla Bugzilla 2.20.4

Bugzilla 2.x before 2.22.7, 3.0 before 3.0.7, 3.2 before 3.2.1, and 3.3 before 3.3.2 allows remote authenticated users to conduct cross-site scripting (XSS) and related attacks by uploading HTML and JavaScript attachments that are rendered by web browsers.

CRLF injection vulnerability in Bugzilla before 3.2.9, 3.4.x before 3.4.9, 3.6.x before 3.6.3, and 4.0.x before 4.0rc1, when Server Push is enabled in a web browser, allows remote attackers to inject arbitrary HTTP headers and content, and conduct HTTP response splitting attacks, via a crafted URL.

Bugzilla 2.20.x before 2.20.5, 2.22.x before 2.22.3, and 3.0.x before 3.0.3 on Windows does not delete the temporary files associated with uploaded attachments, which allows local users to obtain sensitive information by reading these files, a different vulnerability than CVE-2011-2977.
