Mozilla Firefox Multiple Security Vulnerabilities

Mozilla Firefox is prone to the following vulnerabilities:

1. A same-origin security-bypass vulnerability
2. A security-bypass vulnerability
3. A heap buffer-overflow vulnerability
4. Multiple denial-of-service vulnerabilities

Attackers can exploit these issues to bypass security restrictions and perform unauthorized actions, obtain sensitive information, bypass same-origin policy restrictions to access data, and execute arbitrary code in the context of the affected application. Failed exploit attempts will likely result in denial-of-service conditions.

These issues are fixed in:

Firefox 48
Firefox ESR 45.3
