Cross-site scripting (XSS) vulnerability in Bugzilla 3.7.1, 3.7.2, 3.7.3, and 4.0rc1 allows remote attackers to inject arbitrary web script or HTML via the real name field of a user account, related to the AutoComplete widget in YUI.

Bugzilla before 3.2.10, 3.4.x before 3.4.10, 3.6.x before 3.6.4, and 4.0.x before 4.0rc2 does not properly handle whitespace preceding a (1) javascript: or (2) data: URI, which allows remote attackers to conduct cross-site scripting (XSS) attacks via the URL (aka bug_file_loc) field.

Bugzilla before 3.2.10, 3.4.x before 3.4.10, 3.6.x before 3.6.4, and 4.0.x before 4.0rc2 creates a clickable link for a (1) javascript: or (2) data: URI in the URL (aka bug_file_loc) field, which allows remote attackers to conduct cross-site scripting (XSS) attacks against logged-out users via a crafted URI.

The Old Charts implementation in Bugzilla 2.12 through 3.2.8, 3.4.8, 3.6.2, 3.7.3, and 4.1 creates graph files with predictable names in graphs/, which allows remote attackers to obtain sensitive information via a modified URL.

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.

The sudo feature in Bugzilla 2.22rc1 through 3.2.7, 3.3.1 through 3.4.7, 3.5.1 through 3.6.1, and 3.7 through 3.7.2 does not properly send impersonation notifications, which makes it easier for remote authenticated users to impersonate other users without discovery.

Bugzilla 2.17.1 through 3.2.7, 3.3.1 through 3.4.7, 3.5.1 through 3.6.1, and 3.7 through 3.7.2 generates different error messages depending on whether a product exists, which makes it easier for remote attackers to guess product names via unspecified use of the (1) Reports or (2) Duplicates page.

Bugzilla 2.23.1 through 3.2.7, 3.3.1 through 3.4.7, 3.5.1 through 3.6.1, and 3.7 through 3.7.2, when PostgreSQL is used, does not properly handle large integers in (1) bug and (2) attachment phrases, which allows remote authenticated users to cause a denial of service (bug invisibility) via a crafted comment.

Search.pm in Bugzilla 2.19.1 through 3.2.7, 3.3.1 through 3.4.7, 3.5.1 through 3.6.1, and 3.7 through 3.7.2 allows remote attackers to determine the group memberships of arbitrary users via vectors involving the Search interface, boolean charts, and group-based pronouns.

Install/Filesystem.pm in Bugzilla 3.5.1 through 3.6 and 3.7, when use_suexec is enabled, uses world-readable permissions for the localconfig files, which allows local users to read sensitive configuration fields, as demonstrated by the database password field and the site_wide_secret field.
