Gentoo Linux Security Advisory

Title: Bugzilla: Multiple Vulnerabilities (GLSA 200611-04)
Severity: normal
Exploitable: remote
Date: November 09, 2006
Bug(s): #151563
ID: 200611-04

Synopsis

Bugzilla is vulnerable to cross-site scripting, script injection, and request forgery.

Background

Bugzilla is a bug tracking system used to allow developers to more easily track outstanding bugs in products.

Affected Packages

Package: www-apps/bugzilla
Vulnerable: < 2.18.6
Unaffected: >= 2.18.6
Architectures: All supported architectures


Description

The vulnerabilities identified in Bugzilla are as follows:
  • Frederic Buclin and Gervase Markham discovered that input passed to various fields throughout Bugzilla were not properly sanitized before being sent back to users (CVE-2006-5453).
  • Frederic Buclin and Josh "timeless" Soref discovered a bug when viewing attachments in diff mode that allows users not of the "insidergroup" to read attachment descriptions. Additionally, it was discovered that the "deadline" field is visible to users who do not belong to the "timetrackinggroup" when bugs are exported to XML (CVE-2006-5454).
  • Gavin Shelley reported that Bugzilla allows certain operations to be performed via HTTP GET and HTTP POST requests without verifying those requests properly (CVE-2006-5455).
  • Max Kanat-Alexander discovered that input passed to showdependencygraph.cgi is not properly sanitized before being returned to users (CVE-2006-5453).


Impact

An attacker could inject scripts into the content loaded by a user's browser in order to have those scripts executed in a user's browser in the context of the site currently being viewed. This could include gaining access to privileged session information for the site being viewed. Additionally, a user could forge an HTTP request in order to create, modify, or delete bugs within a Bugzilla instance. Lastly, an unauthorized user could view sensitive information about bugs or bug attachments.

Workaround

There is no known workaround at this time.

Resolution

All Bugzilla users should upgrade to the latest version:
Code:
# emerge --sync
# emerge --ask --oneshot --verbose ">=www-apps/bugzilla-2.18.6"
