Title: Linux kernel vulnerabilities
Summary: Several security issues were fixed in the Linux kernel.
Qian Zhang discovered a heap-based buffer overflow in the tipc_msg_build()

CVE-2017-10662 [HIGH] CWE-391 kernel: Missing sanity check for segment count in f2fs
kernel: Missing sanity check for segment count in f2fs
The sanity_check_raw_super function in fs/f2fs/super.c in the Linux kernel before 4.11.1 does not validate the segment count, which allows local users to gain privileges via unspecified vectors.
It was found that the sanity_check_raw_super() function in 'fs/f2fs/super.c' file in the Linux kernel before version 4.12-rc1 does not validate the f2fs filesystem segment count. This allows an unprivileged local user to cause a system panic and DoS. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is unlikely.

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
