Mozilla Addresses Multiple Vulnerabilities
Original release date: December 20, 2006
Last revised: --
Source: US-CERT
Systems Affected
* Mozilla Firefox
* Mozilla Thunderbird
* Mozilla SeaMonkey
* Netscape Browser
Other products based on Mozilla components may also be affected.
Overview
The Mozilla web browser and derived products contain several
vulnerabilities, the most severe of which could allow a remote
attacker to execute arbitrary code on an affected system.
I. Description
Mozilla has released new versions of Firefox, Thunderbird, and
SeaMonkey to address several vulnerabilities. Further details about
these vulnerabilities are available from Mozilla and the
Vulnerability Notes Database. An attacker could exploit these
vulnerabilities by convincing a user to view a specially-crafted
HTML document, such as a web page or HTML email message.
II. Impact
While the impacts of the individual vulnerabilities vary, the most
severe could allow a remote, unauthenticated attacker to execute
arbitrary code on a vulnerable system. An attacker may also be able
to cause a denial of service.
III. Solution
Upgrade
These vulnerabilities are addressed in Mozilla Firefox 1.5.0.9,
Mozilla Firefox 2.0.0.1, Mozilla Thunderbird 1.5.0.9, and SeaMonkey
1.0.7. Mozilla Firefox, Thunderbird, and SeaMonkey automatically
check for updates by default.
Support for Firefox 1.5 is scheduled to end in April
2007. According to Mozilla:
Firefox 1.5.0.x will be maintained with security and stability
updates until April 24, 2007. All users are strongly encouraged
to upgrade to Firefox 2.
Disable JavaScript and Java
These vulnerabilities can be mitigated by disabling JavaScript and
Java. For more information about configuring Firefox, please see
the "Securing Your Web Browser" document. Netscape users should see
the "Site Controls" document for details. Thunderbird disables
JavaScript and Java by default.
