A Bugzilla Security Advisory reports:

The following security issues have been discovered in Bugzilla:

Information Leak

If the visibility of a custom field is controlled by a product or a component of a product you cannot see, their names are disclosed in the JavaScript code generated for this custom field despite they should remain confidential.

Calling the User.get method with a 'groups' argument leaks the existence of the groups depending on whether an error is thrown or not. This method now also throws an error if the user calling this method does not belong to these groups (independently of whether the groups exist or not).

Trying to mark an attachment in a bug you cannot see as obsolete discloses its description in the error message. The description of the attachment is now removed from the error message.

Cross-Site Scripting

Due to incorrectly filtered field values in tabular reports, it is possible to inject code leading to XSS.

A vulnerability in swfstore.swf from YUI2 allows JavaScript injection exploits to be created against domains that host this affected YUI .swf file.

A Bugzilla Security Advisory reports:

The following security issues have been discovered in Bugzilla:

Unauthorized Access

Due to a lack of proper validation of the X-FORWARDED-FOR header of an authentication request, an attacker could bypass the current lockout policy used for protection against brute- force password discovery. This vulnerability can only be exploited if the 'inbound_proxies' parameter is set.

Cross Site Scripting

A JavaScript template used by buglist.cgi could be used by a malicious script to permit an attacker to gain access to some information about bugs he would not normally be allowed to see, using the victim's credentials. To be exploitable, the victim must be logged in when visiting the attacker's malicious page.

All affected installations are encouraged to upgrade as soon as possible.

A Bugzilla Security Advisory reports:

The following security issues have been discovered in Bugzilla:

• Due to a lack of validation of the enctype form attribute when making POST requests to xmlrpc.cgi, a possible CSRF vulnerability was discovered. If a user visits an HTML page with some malicious HTML code in it, an attacker could make changes to a remote Bugzilla installation on behalf of the victim's account by using the XML-RPC API on a site running mod_perl. Sites running under mod_cgi are not affected. Also, the user would have had to be already logged in to the target site for the vulnerability to work.

All affected installations are encouraged to upgrade as soon as possible.

A Bugzilla Security Advisory reports:

The following security issues have been discovered in Bugzilla:

LDAP Injection

When the user logs in using LDAP, the username is not escaped when building the uid=$username filter which is used to query the LDAP directory. This could potentially lead to LDAP injection.

Directory Browsing

Extensions are not protected against directory browsing and users can access the source code of the templates which may contain sensitive data. Directory browsing is blocked in Bugzilla 4.3.3 only, because it requires a configuration change in the Apache httpd.conf file to allow local .htaccess files to use Options -Indexes. To not break existing installations, this fix has not been backported to stable branches. The access to templates is blocked for all supported branches except the old 3.6 branch, because this branch doesn't have .htaccess in the bzr repository and cannot be fixed easily for existing installations without potentially conflicting with custom changes.
