Bugzilla 2.x and 3.x through 3.6.11, 3.7.x and 4.0.x before 4.0.8, 4.1.x and 4.2.x before 4.2.3, and 4.3.x before 4.3.3 stores potentially sensitive information under the web root with insufficient access control, which allows remote attackers to read (1) template (aka .tmpl) files, (2) other custom extension files under extensions/, or (3) custom documentation files under docs/ via a direct request.

Auth/Verify/LDAP.pm in Bugzilla 2.x and 3.x before 3.6.11, 3.7.x and 4.0.x before 4.0.8, 4.1.x and 4.2.x before 4.2.3, and 4.3.x before 4.3.3 does not restrict the characters in a username, which might allow remote attackers to inject data into an LDAP directory via a crafted login attempt.
