Published on: 23 October 2019

  
  

Description:

Mozilla has published two security advisories (MFSA 2019-33 and MFSA 2019-34) to address multiple browser vulnerabilities.  A remote attacker could entice a user running a vulnerable browser to open a web page with specially crafted content to exploit the vulnerabilities.

 

Affected Systems:

  • Firefox prior to version 70
  • Firefox ESR prior to version 68.2

 

Impact:

Successful exploitation of the vulnerabilities could lead to arbitrary code execution, security restriction bypass, cross-site scripting, memory corruption 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 70 for Windows, Macintosh and Linux
    https://www.mozilla.org/en-US/firefox/all/

  • Firefox ESR 68.2 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.
