Mozilla Updates for Multiple Vulnerabilities
Original release date: July 18, 2007
Last revised: --
Source: US-CERT
Systems Affected
* Mozilla Firefox
* Mozilla Thunderbird
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 and Thunderbird 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 an 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 or obtain private information.
III. Solution
Upgrade
These vulnerabilities are addressed in Mozilla Firefox 2.0.0.5 and
Thunderbird 2.0.0.5.
Disable JavaScript
Some of these vulnerabilities can be mitigated by disabling JavaScript
or using the NoScript extension. For more information about
configuring Firefox, please see the Securing Your Web Browser
document. Thunderbird disables JavaScript and Java by default.
