Description:

Mozilla has published security advisories to address multiple vulnerabilities found in Firefox.  These vulnerabilities are caused by buffer overflow, memory safety bugs, origin confusion, out-of-bounds read and write, use-after-free error, etc.  A remote attacker could entice a user to open a web page with specially crafted content to exploit the vulnerabilities.

 

Affected Systems:

  • Firefox ESR prior to version 45.9
  • Firefox ESR prior to version 52.1

 

Impact:

A successful attack could lead to allow cross-site scripting, denial of service, arbitrary code execution, security restriction bypass, spoofing or application crash 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 53 for Windows, Macintosh and Linux
    https://www.mozilla.org/en-US/firefox/all.html

  • Firefox ESR 52.1 and Firefox ESR 45.9 for Windows, Macintosh and Linux
