Summary
USN-3291-1 fixed vulnerabilities in the generic Linux kernel.
This update provides the corresponding updates for the Linux kernel
built for specific processors and cloud environments.
Dmitry Vyukov discovered that the generic SCSI (sg) subsystem in the Linux
kernel contained a stack-based buffer overflow. A local attacker with
access to an sg device could use this to cause a denial of service (system
crash) or possibly execute arbitrary code. (CVE-2017-7187)
It was discovered that a NULL pointer dereference existed in the Direct
Rendering Manager (DRM) driver for VMWare devices in the Linux kernel. A
local attacker could use this to cause a denial of service (system crash).
(CVE-2017-7261)
Li Qiang discovered that an integer overflow vulnerability existed in the
Direct Rendering Manager (DRM) driver for VMWare devices in the Linux
kernel. A local attacker could use this to cause a denial of service
(system crash) or possibly execute arbitrary code. (CVE-2017-7294)
It was discovered that an information leak existed in the set_mempolicy and
mbind compat syscalls in the Linux kernel. A local attacker could use this
to expose sensitive information (kernel memory). (CVE-2017-7616)
