Summary
Qian Zhang discovered a heap-based buffer overflow in the tipc_msg_build()
function in the Linux kernel. A local attacker could use to cause a denial
of service (system crash) or possibly execute arbitrary code with
administrative privileges. (CVE-2016-8632)
Dmitry Vyukov discovered that a race condition existed in the timerfd
subsystem of the Linux kernel when handling might_cancel queuing. A local
attacker could use this to cause a denial of service (system crash) or
possibly execute arbitrary code. (CVE-2017-10661)
It was discovered that the Flash-Friendly File System (f2fs) implementation
in the Linux kernel did not properly validate superblock metadata. A local
attacker could use this to cause a denial of service (system crash) or
possibly execute arbitrary code. (CVE-2017-10662, CVE-2017-10663)
Anthony Perard discovered that the Xen virtual block driver did not
properly initialize some data structures before passing them to user space.
A local attacker in a guest VM could use this to expose sensitive
information from the host OS or other guest VMs. (CVE-2017-10911)
It was discovered that a use-after-free vulnerability existed in the POSIX
message queue implementation in the Linux kernel. A local attacker could
use this to cause a denial of service (system crash) or possibly execute
arbitrary code. (CVE-2017-11176)
Dave Chinner discovered that the XFS filesystem did not enforce that the
realtime inode flag was settable only on filesystems on a realtime device.
A local attacker could use this to cause a denial of service (system
crash). (CVE-2017-14340)
