Mozilla Firefox < 1.7.6 Multiple Vulnerabilities

Medium

Synopsis

The remote host is missing a critical security patch or upgrade.

Description

stripped_description=Versions of Mozilla Firefox prior to 1.7.6 are affected by the following vulnerabilities :

- There is a flaw in the way that the browser handles scripting within 'tabbed' cross-domains. An attacker exploiting this flaw would need to be able to convince a user to click on a malicious URL which would then open a separate 'TAB' within the browser. The attacker could then retrieve data relevant to other tabbed connections or execute code locally. - There is a flaw in the default 'about: config' script that would allow an attacker to modify configuration data. In order to execute such an attack, the attacker would need to be able to entice the user into visiting or clicking on a malicious URL. A successful attacker would be able to modify the local configuration file, resulting in enhanced access rights or other potential exploits. In addition, there are other unconfirmed flaws in Mozilla version 1.7.5 and lower.

Solution

Upgrade to Mozilla Firefox 1.7.6 or later.
