[USN-3265-1] Linux kernel vulnerabilities

Severity High
Affected Packages 13
CVEs 10
Info Packages Vulnerabilities

Several security issues were fixed in the kernel.

It was discovered that a use-after-free flaw existed in the filesystem
encryption subsystem in the Linux kernel. A local attacker could use this
to cause a denial of service (system crash). (CVE-2017-7374)

Andrey Konovalov discovered an out-of-bounds access in the IPv6 Generic
Routing Encapsulation (GRE) tunneling implementation in the Linux kernel.
An attacker could use this to possibly expose sensitive information.
(CVE-2017-5897)

Andrey Konovalov discovered that the IPv4 implementation in the Linux
kernel did not properly handle invalid IP options in some situations. An
attacker could use this to cause a denial of service or possibly execute
arbitrary code. (CVE-2017-5970)

Gareth Evans discovered that the shm IPC subsystem in the Linux kernel did
not properly restrict mapping page zero. A local privileged attacker could
use this to execute arbitrary code. (CVE-2017-5669)

Alexander Popov discovered that a race condition existed in the Stream
Control Transmission Protocol (SCTP) implementation in the Linux kernel. A
local attacker could use this to cause a denial of service (system crash).
(CVE-2017-5986)

Dmitry Vyukov discovered that the Linux kernel did not properly handle TCP
packets with the URG flag. A remote attacker could use this to cause a
denial of service. (CVE-2017-6214)

Andrey Konovalov discovered that the LLC subsytem in the Linux kernel did
not properly set up a destructor in certain situations. A local attacker
could use this to cause a denial of service (system crash). (CVE-2017-6345)

It was discovered that a race condition existed in the AF_PACKET handling
code in the Linux kernel. A local attacker could use this to cause a denial
of service (system crash) or possibly execute arbitrary code.
(CVE-2017-6346)

Andrey Konovalov discovered that the IP layer in the Linux kernel made
improper assumptions about internal data layout when performing checksums.
A local attacker could use this to cause a denial of service (system crash)
or possibly execute arbitrary code. (CVE-2017-6347)

Dmitry Vyukov discovered race conditions in the Infrared (IrDA) subsystem
in the Linux kernel. A local attacker could use this to cause a denial of
service (deadlock). (CVE-2017-6348)
