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

Mozilla has released new versions of the product to address the issues and they can be downloaded at the following URLs:
Users of affected systems should follow the recommendations provided by the product vendor and take immediate actions to mitigate the risk.
