Description:

Mozilla has published three security advisories (MFSA 2019-25, MFSA 2019-26 and MFSA 2019-27) 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 69
  • Firefox ESR prior to version 60.9
  • Firefox ESR prior to version 68.1

 

Impact:

Successful exploitation of the vulnerabilities could lead to arbitrary code execution, security restriction bypass, information disclosure, data tampering, privilege escalation, 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 69 for Windows, Macintosh and Linux
    https://www.mozilla.org/en-US/firefox/all/

  • Firefox ESR 60.9 and 68.1 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.
