Extension of fuzzing for Linux disk encryption

Extension of fuzzing for Linux disk encryption
Abstract:
Šifrování disku je mocný nástroj pro oblasti pracující s citlivými informacemi. Je nezbytné se ujistit, že tyto nástroje jsou bezpečné a bez chyb. Aktuálně populárním způsobem detekce bezpečnostních chyb v aplikacích je fuzzing. Tato práce se zaobírá existující infrastrukturou pro fuzzing za pomocí OSS-Fuzz v nástroji cryptsetup a dále ji rozšiřuje. Nalezené problémy v nástroji util-linux nás vedly …more

Disk encryption is a powerful tool for sectors handling sensitive in- formation. It is essential to ensure these tools are secure and void of bugs. A recently popular way to detect security flaws in applications is fuzzing. This thesis looks at the existing fuzzing infrastructure us- ing OSS-Fuzz in the cryptsetup utility and extends it further. Issue discoveries in the util-linux utility also lead …more
