CVE-2018-13097 [MEDIUM] Linux kernel vulnerabilities
Title: Linux kernel vulnerabilities
Summary: Several security issues were fixed in the Linux kernel.
It was discovered that the timer stats implementation in the Linux kernel
allowed the discovery of a real PID value while inside a PID namespace. A
local attacker could use this to expose sensitive information.
(CVE-2017-5967)
Wen Xu discovered that the XFS file system implementation in the Linux
kernel did not properly track inode validations. An attacker could use this
to construct a malicious XFS image that, when mounted, could cause a denial
of service (system crash). (CVE-2018-13093)
Wen Xu discovered that the f2fs file system implementation in the Linux
kernel did not properly validate metadata. An attacker could use this to
construct a malicious f2fs image that, when mounted, cou
