Published on: 12 February 2016

  
  

Description:

Mozilla has published security advisories to address multiple vulnerabilities found in Firefox. These vulnerabilities are caused by circumventing the validation of internal instruction parameters in the Graphite 2 and violating the same-origin-policy using Service Workers with plugins. A remote attacker could entice a user to open a web page with specially crafted content to exploit the vulnerabilities.


Affected Systems:

  • Firefox prior to version 44.0.2
  • Firefox ESR 38.x prior to version 38.6.1

Impact:

A successful attack could lead to arbitrary code execution on an affected system.


Recommendation:

Mozilla has released new versions of the product to address the issues and they can be downloaded at the following URLs:

  • Firefox 44.0.2 for Windows, Macintosh and Linux
    http://www.mozilla.org/en-US/firefox/all.html

  • Firefox ESR 38.6.1 for Windows, Macintosh and Linux
    https://www.mozilla.org/en-US/firefox/organizations/all/

Users of affected systems should follow the recommendations provided by the product vendor and take immediate actions to mitigate the risk.
