Upgrades released to protect users

Multiple security flaws in Bugzilla could put users of the software-defect--tracking product at risk of cross-site scripting, data manipulation and data exposure attacks.

According to a warning from the Mozilla Foundations open-source Bugzilla project, users should immediately upgrade to versions 2.18.6, 2.20.3, 2.22.1 or 2.23.3 to minimize the risk of malicious attacks.

Security alerts aggregator Secunia on Oct. 16 rated the vulnerabilities as "moderately critical."

The most serious vulnerability occurs because Bugzilla does not properly sanitize various fields when embedded in certain HTML headline tags.

"This can be exploited to execute arbitrary HTML and script code in a users browser session in [the] context of an affected site," Secunia analysts warned.

A second error that happens when attachments in "diff" mode are viewed could let unauthenticated users read the descriptions of all attachments.

In addition, when exporting bugs to the XML format, the "deadline" field also is visible to users who are not members of the "timetracking-group" group. This can be exploited to gain knowledge of potentially sensitive information, Secunia analysts explained. This could allow a malicious user to pass a URL to an administrator and make the administrator delete or change something that he or she had not intended to delete or change.

Unpatched versions of Bugzilla also allow users to perform certain sensitive actions via HTTP GET and POST requests without verifying the users request properly. This can be exploited to modify, delete or create bugs.

Bugzilla is a free, Web-based tool used by software developers to track code bugs and defects, and it is widely used in the open-source community. According to Bugzillas Web site, it has been identified as being used by 546 companies, organizations and projects.

The free software projects that use Bugzilla include the Linux kernel, GNOME, KDE, Apache, OpenOffice.org and Eclipse.

Bugzilla also is used in major Linux distributions from Red Hat, Mandriva, Gentoo Foundation, Turbo-linux and Novells SUSE unit.

Major companies and government agencies that use Bugzilla include Ximian, NASA and Id Software.
