The Security War in File Systems: An Empirical Study from A Vulnerability-Centric Perspective
## Abstract
This paper presents a systematic study on the security of modern file systems,
following a vulnerability-centric perspective. Specifically,
we collected 377 file system vulnerabilities committed to the CVE database in the past 20 years.
We characterize them from four dimensions that include why the vulnerabilities appear,
how the vulnerabilities can be exploited, what consequences can arise,
and how the vulnerabilities are fixed. This way, we build a deep understanding of
the attack surfaces faced by file systems, the threats imposed by the attack surfaces,
and the good and bad practices in mitigating the attacks in file systems. We envision that our study
will bring insights toward
