CVE-2016-9555 [CRITICAL] Linux kernel (OMAP4) vulnerabilities
Title: Linux kernel (OMAP4) vulnerabilities
Summary: Several security issues were fixed in the kernel.
Andrey Konovalov discovered that the SCTP implementation in the Linux
kernel improperly handled validation of incoming data. A remote attacker
could use this to cause a denial of service (system crash). (CVE-2016-9555)
It was discovered that multiple memory leaks existed in the XFS
implementation in the Linux kernel. A local attacker could use this to
cause a denial of service (memory consumption). (CVE-2016-9685)
Instructions: After a standard system update you need to reboot your computer to make
all the necessary changes.
ATTENTION: Due to an unavoidable ABI change the kernel updates have
been given a new version number, which requires you to recompile and
reinstall all third part

CVE-2016-9685 [MEDIUM] CWE-772 kernel: Memory leaks in xfs_attr_list.c error paths
kernel: Memory leaks in xfs_attr_list.c error paths
Multiple memory leaks in error paths in fs/xfs/xfs_attr_list.c in the Linux kernel before 4.5.1 allow local users to cause a denial of service (memory consumption) via crafted XFS filesystem operations.
A flaw was found in the Linux kernel's implementation of XFS file attributes. Two memory leaks were detected in xfs_attr_shortform_list and xfs_attr3_leaf_list_int when running a docker container backed by xfs/overlay2. A dedicated attacker could possible exhaust all memory and create a denial of service situation.
Statement: This issue affects the Linux kernel packages as shipped with Red Hat Enterprise Linux 5 and 6 and 7. This has been rated as having Low security impact and is not currently planned to be addressed in future updates.

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
