Cross-site scripting (XSS) vulnerability in the Flash component infrastructure in YUI 2.5.0 through 2.8.1, as used in Bugzilla, Moodle, and other products, allows remote attackers to inject arbitrary web script or HTML via vectors related to uploader/assets/uploader.swf.

Cross-site scripting (XSS) vulnerability in the Flash component infrastructure in YUI 2.8.0 through 2.8.1, as used in Bugzilla 3.7.1 through 3.7.3 and 4.1, allows remote attackers to inject arbitrary web script or HTML via vectors related to swfstore/swfstore.swf.

Cross-site scripting (XSS) vulnerability in the Flash component infrastructure in YUI 2.4.0 through 2.8.1, as used in Bugzilla, Moodle, and other products, allows remote attackers to inject arbitrary web script or HTML via vectors related to charts/assets/charts.swf.

Multiple cross-site request forgery (CSRF) vulnerabilities in 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 allow remote attackers to hijack the authentication of arbitrary users for requests related to (1) adding a saved search in buglist.cgi, (2) voting in votes.cgi, (3) sanity checking in sanitycheck.cgi, (4) creating or editing a chart in chart.cgi, (5) column changing in colchange.cgi, and (6) adding, deleting, or approving a quip in quips.cgi.

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 bugfileloc) field, which allows remote attackers to conduct cross-site scripting (XSS) attacks against logged-out users via a crafted URI.

Upstream Bugzilla has released 3.4.8 and 3.6.2 to address four security flaws [1]:

Vulnerability Details =====================

Class: Remote Information Disclosure Versions: 2.19.1 to 3.2.7, 3.3.1 to 3.4.7, 3.5.1 to 3.6.1, 3.7 to 3.7.2 Fixed In: 3.2.8, 3.4.8, 3.6.2, 3.7.3 Description: An unprivileged user is normally not allowed to view other users' group membership. But boolean charts let the user use group-based pronouns, indirectly disclosing group membership. This security fix restricts the use of pronouns to groups the user belongs to. References: https://bugzilla.mozilla.org/showbug.cgi?id=417048 CVE Number: CVE-2010-2756

Class: Notification Bypass Versions: 2.22rc1 to 3.2.7, 3.3.1 to 3.4.7, 3.5.1 to 3.6.1, 3.7 to 3.7.2 Fixed In: 3.2.8, 3.4.8, 3.6.2, 3.7.3 Description: Normally, when a user is impersonated, he receives an email informing him that he is being impersonated, containing the identity of the impersonator. However, it was possible to impersonate a user without this notification being sent. References: https://bugzilla.mozilla.org/showbug.cgi?id=450013 CVE Number: CVE-2010-2757

Class: Remote Information Disclosure Versions: 2.17.1 to 3.2.7, 3.3.1 to 3.4.7, 3.5.1 to 3.6.1, 3.7 to 3.7.2 Fixed In: 3.2.8, 3.4.8, 3.6.2, 3.7.3 Description: An error message thrown by the "Reports" and "Duplicates" page confirmed the non-existence of products, thus allowing users to guess confidential product names. (Note that the "Duplicates" page was not vulnerable in Bugzilla 3.6rc1 and above though.) References: https://bugzilla.mozilla.org/showbug.cgi?id=577139 https://bugzilla.mozilla.org/showbug.cgi?id=519835 CVE Number: CVE-2010-2758

Class: Denial of Service Versions: 2.23.1 to 3.2.7, 3.3.1 to 3.4.7, 3.5.1 to 3.6.1, 3.7 to 3.7.2 Fixed In: 3.2.8, 3.4.8, 3.6.2, 3.7.3 Description: If a comment contained the phrases "bug X" or "attachment X", where X was an integer larger than the maximum 32-bit signed integer size, PostgreSQL would throw an error, and any page containing that comment would not be viewable. On most Bugzillas, any user can enter a comment on any bug, so any user could have used this to deny access to one or all bugs. Bugzillas running on databases other than PostgreSQL are not affected.
