Title:Mozilla Firefox Security Advisory (MFSA2012-93) - Linux
Summary:This host is missing a security update for Mozilla Firefox.
Description:Summary:
This host is missing a security update for Mozilla Firefox.

Vulnerability Insight:
evalInSanbox location context incorrectly applied
Mozilla security researcher moz_bug_r_a4 reported that if code executed by the evalInSandbox function sets location.href, it can get the wrong subject principal for the URL check, ignoring the sandbox's Javascript context and gaining the context of evalInSandbox object. This can lead to malicious web content being able to perform a cross-site scripting (XSS) attack or stealing a copy of a local file if the user has installed an add-on vulnerable to this attack.

Affected Software/OS:
Firefox version(s) below 17.

Solution:
The vendor has released an update. Please see the reference(s) for more information.

CVSS Score:
4.3
