Fat Pointers for Temporal Memory Safety of C. (arXiv:2208.12900v1 [cs.CR])

Temporal memory safety bugs, especially use-after-free and double free bugs,
pose a major security threat to C programs. Real-world exploits utilizing these
bugs enable attackers to read and write arbitrary memory locations, causing
disastrous violations of confidentiality, integrity, and availability. Many
previous solutions retrofit temporal memory safety to C, but they all either
incur high performance overhead and/or miss detecting certain types of temporal
memory safety bugs.

In this paper, we propose a temporal memory safety solution that is both …
