Snapshots for IPC Fuzzing

**Snapshots for IPC Fuzzing**

Process separation is one of the cornerstones of the Firefox security model. Instead of running Firefox as a single process, multiple processes with different privileges communicate with each other via Inter-Process Communication (IPC). For example: loading a website, processing its resources, and rendering it is done by an isolated Content Process with a very restrictive sandbox, whereas critical operations such as file system access are only allowed to be executed in the Parent Process. By running potentially harmful code with lower privileges, the impact of a potential code execution vulnerability is mitigated. In order to gain full control, the attacker now needs to find a second vulnerability that allows bypassing these privilege restrictions – which is colloquially known as a “sandbox escape”...
