Published: 2017-06-15 11:53:17
CVE Author: NIST National Vulnerability Database

CVSS Base Vector:

This host is installed with Mozilla Firefox and is prone to multiple vulnerabilities.

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

Technical Details:
The multiple flaws exists due to, - Use-after-free using destroyed node when regenerating trees. - Use-after-free during docshell reloading. - Use-after-free with track elements. - Use-after-free with content viewer listeners. - Use-after-free with IME input. - Out-of-bounds read in WebGL with ImageInfo object. - Privilege escalation through Firefox Installer with same directory DLL files. - Use-after-free and use-after-scope logging XHR header errors. - Use-after-free in IndexedDB. - Vulnerabilities in the Graphite 2 library. - Out-of-bounds read in Opus encoder. - Android intent URLs can cause navigation to local file system. - File manipulation and privilege escalation via callback parameter in Mozilla Windows Updater and Maintenance Service. - File deletion and privilege escalation through Mozilla Maintenance Service helper.exe application. - Addressbar spoofing in Reader mode. - Mac fonts render some unicode characters as spaces. - Domain spoofing with combination of Canadian Syllabics and other unicode blocks. - Mark of the Web bypass when saving executable files. - File execution and privilege escalation through updater.ini, Mozilla Windows Updater, and Mozilla Maintenance Service. - Privilege escalation and arbitrary file overwrites through Mozilla Windows Updater and Mozilla Maintenance Service. - 32 byte arbitrary file read through Mozilla Maintenance Service. - Addressbar spoofing with JavaScript events and fullscreen mode.

Successful exploitation will allow remote attackers to execute arbitrary code, to delete arbitrary files by leveraging certain local file execution, to obtain sensitive information, and to cause a denial of service.

Affected Versions:
Mozilla Firefox version before 54.0 on MAC OS X.

Upgrade to Mozilla Firefox version 54.0 or later.

Solution Type:
Vendor Patch

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".
