SQL injection vulnerability in editusers.cgi in Bugzilla 2.16.x before 2.16.6, and 2.18 before 2.18rc1, allows remote attackers with privileges to grant membership to any group to execute arbitrary SQL.
Multiple cross-site scripting vulnerabilities (XSS) in Bugzilla 2.16.x before 2.16.3 and 2.17.x before 2.17.4 allow remote attackers to insert arbitrary HTML or web script via (1) multiple default German and Russian HTML templates or (2) ALT and NAME attributes in AREA tags as used by the GraphViz graph generation feature for local dependency graphs.
Bugzilla 2.16.x before 2.16.3, 2.17.x before 2.17.4, and earlier versions allows local users to overwrite arbitrary files via a symlink attack on temporary files that are created in directories with group-writable or world-writable permissions.
The data collection script for Bugzilla 2.14.x before 2.14.5, 2.16.x before 2.16.2, and 2.17.x before 2.17.3 sets world-writable permissions for the data/mining directory when it runs, which allows local users to modify or delete the data.
The default .htaccess scripts for Bugzilla 2.14.x before 2.14.5, 2.16.x before 2.16.2, and 2.17.x before 2.17.3 do not include filenames for backup copies of the localconfig file that are made from editors such as vi and Emacs, which could allow remote attackers to obtain a database password by directly accessing the backup file.
Cross-site scripting (XSS) vulnerability in the quips feature in Mozilla Bugzilla 2.10 through 2.17 allows remote attackers to inject arbitrary web script or HTML via the "show all quips" page.
editproducts.cgi in Bugzilla 2.14.x before 2.14.4, and 2.16.x before 2.16.1, when the "usebuggroups" feature is enabled and more than 47 groups are specified, does not properly calculate bit values for large numbers, which grants extra permissions to users via known features of Perl math that set multiple bits.
bugzilla_email_append.pl in Bugzilla 2.14.x before 2.14.4, and 2.16.x before 2.16.1, allows remote attackers to execute arbitrary code via shell metacharacters in a system call to processmail.
Bugzilla 2.16.x before 2.16.1 does not properly filter apostrophes from an email address during account creation, which allows remote attackers to execute arbitrary SQL via a SQL injection attack.
