Mozilla Firefox ESR Multiple Vulnerabilities (Windows)

Published: 2015-08-31 10:54:54
CVE Author: NIST National Vulnerability Database

CVSS Base Vector:
AV:N/AC:L/Au:N/C:C/I:C/A:C

Summary:
This host is installed with Mozilla Firefox ESR and is prone to multiple Vulnerabilities.

Detection Method:
Checks if a vulnerable version is present on the target host.

Technical Details:
Multiple flaws are due to: - A use-after-free vulnerability with a '' element on a page. This occurs when a resize event is triggered in concert with style changes but the canvas references have been recreated in the meantime, destroying the originally referenced context. This results in an exploitable crash. - A vulnerablity in the way Firefox handles installation of add-ons.

Impact:
Successful exploitation will allow remote attackers to execute arbitrary code by leveraging improper interaction between resize events and changes to Cascading Style Sheets (CSS) token sequences for a CANVAS element and to bypass an intended user-confirmation requirement by constructing a crafted data.

Affected Versions:
Mozilla Firefox ESR 38.x before 38.2.1 on Windows

Recommendations:
Upgrade to Mozilla Firefox ESR version 38.2.1 or later.

Solution Type:
Vendor Patch

Detection Type:
Windows Registry

Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
