CVE-2017-5400 is a critical memory corruption vulnerability affecting Mozilla Firefox and Thunderbird versions prior to 52 and 45.8, respectively. It leverages a JIT-spray attack against asm.js, combined with a heap spray, to bypass ASLR and DEP protections. This allows for arbitrary code execution with a CVSS score of 9.8, indicating a network-exploitable vulnerability with high impact on confidentiality, integrity, and availability. While no public exploit code or active exploitation has been observed, and community discussion is minimal, the high FAUCET Risk Score of 80/100 suggests significant potential for impact.
