CVE-2016-5244

Several vulnerabilities have been discovered in the Linux kernel that
may lead to a privilege escalation, denial of service or information
leaks.

CVE-2015-7515, CVE-2016-2184, CVE-2016-2185, CVE-2016-2186,
CVE-2016-2187, CVE-2016-3136, CVE-2016-3137, CVE-2016-3138,
CVE-2016-3140

Ralf Spenneberg of OpenSource Security reported that various USB
drivers do not sufficiently validate USB descriptors. This
allowed a physically present user with a specially designed USB
device to cause a denial of service (crash).

CVE-2016-0821

Solar Designer noted that the list 'poisoning' feature, intended
to mitigate the effects of bugs in list manipulation in the
kernel, used poison values within the range of virtual addresses
that can be allocated by user processes.

CVE-2016-1237

David Sinquin discovered that nfsd does not check permissions when
setting ACLs, allowing users to grant themselves permissions to a
file by setting the ACL.

CVE-2016-1583

Jann Horn of Google Project Zero reported that the eCryptfs
filesystem could be used together with the proc filesystem to
cause a kernel stack overflow. If the ecryptfs-utils package is
installed, local users could exploit this, via the
mount.ecryptfs_private program, for denial of service (crash) or
possibly for privilege escalation.

CVE-2016-2117

Justin Yackoski of Cryptonite discovered that the Atheros L2
ethernet driver incorrectly enables scatter/gather I/O. A remote
attacker could take advantage of this flaw to obtain potentially
sensitive information from kernel memory.

CVE-2016-2143

Marcin Koscielnicki discovered that the fork implementation in the
Linux kernel on s390 platforms mishandles the case of four
page-table levels, which allows local users to cause a denial of
service (system crash).

CVE-2016-3070

Jan Stancek of Red Hat discovered a local denial of service
vulnerability in AIO handling.

CVE-2016-3134

The Google Project Zero team found that the netfilter subsystem does
not sufficiently validate filter table entries. A user with the
CAP_NET_ADMIN capability could use this for denial of service
(crash) or possibly for privilege escalation. Debian disables
unprivileged user namespaces by default, if locally enabled with the
kernel.unprivileged_userns_clone sysctl, this allows privilege
escalation.

CVE-2016-3156

Solar Designer discovered that the IPv4 implementation in the Linux
kernel did not perform the destruction of inet device objects
properly. An attacker in a guest OS could use this to cause a denial
of service (networking outage) in the host OS.

CVE-2016-3157 / XSA-171

Andy Lutomirski discovered that the x86_64 (amd64) task switching
implementation did not correctly update the I/O permission level
when running as a Xen paravirtual (PV) guest. In some
configurations this would allow local users to cause a denial of
service (crash) or to escalate their privileges within the guest.

CVE-2016-3672

Hector Marco and Ismael Ripoll noted that it was possible to disable
Address Space Layout Randomisation (ASLR) for x86_32 (i386) programs
by removing the stack resource limit. This made it easier for local
users to exploit security flaws in programs that have the setuid or
setgid flag set.

CVE-2016-3951

It was discovered that the cdc_ncm driver would free memory
prematurely if certain errors occurred during its initialisation.
This allowed a physically present user with a specially designed
USB device to cause a denial of service (crash) or possibly to
escalate their privileges.

CVE-2016-3955

Ignat Korchagin reported that the usbip subsystem did not check
the length of data received for a USB buffer. This allowed denial
of service (crash) or privilege escalation on a system configured
as a usbip client, by the usbip server or by an attacker able to
impersonate it over the network. A system configured as a usbip
server might be similarly vulnerable to physically present users.

CVE-2016-3961 / XSA-174

Vitaly Kuznetsov of Red Hat discovered that Linux allowed the use of
hugetlbfs on x86 (i386 and amd64) systems even when running as a Xen
paravirtualised (PV) guest, although Xen does not support huge
pages. This allowed users with access to /dev/hugepages to cause a
denial of service (crash) in the guest.

CVE-2016-4470

David Howells of Red Hat discovered that a local user can trigger a
flaw in the Linux kernel's handling of key lookups in the keychain
subsystem, leading to a denial of service (crash) or possibly to
privilege escalation.

CVE-2016-4482, CVE-2016-4485, CVE-2016-4486, CVE-2016-4569,
CVE-2016-4578, CVE-2016-4580, CVE-2016-5243, CVE-2016-5244

Kangjie Lu reported that the USB devio, llc, rtnetlink, ALSA
timer, x25, tipc, and rds facilities leaked information from the
kernel stack.

CVE-2016-4565

Jann Horn of Google Project Zero reported that various components
in the InfiniBand stack implemented unusual semantics for the
write() operation. On a system with InfiniBand drivers loaded,
local users could use this for denial of service or privilege
escalation.

CVE-2016-4581

Tycho Andersen discovered that in some situations the Linux kernel
did not handle propagated mounts correctly. A local user can take
advantage of this flaw to cause a denial of service (system crash).

CVE-2016-4805

Baozeng Ding discovered a use-after-free in the generic PPP layer in
the Linux kernel. A local user can take advantage of this flaw to
cause a denial of service (system crash), or potentially escalate
their privileges.

CVE-2016-4913

Al Viro found that the ISO9660 filesystem implementation did not
correctly count the length of certain invalid name entries.
Reading a directory containing such name entries would leak
information from kernel memory. Users permitted to mount disks or
disk images could use this to obtain sensitive information.

CVE-2016-4997 / CVE-2016-4998

Jesse Hertz and Tim Newsham discovered that missing input sanitising
in Netfilter socket handling may result in denial of service. Debian
disables unprivileged user namespaces by default, if locally enabled
with the kernel.unprivileged_userns_clone sysctl, this also allows
privilege escalation.

For the stable distribution (jessie), these problems have been fixed in
version 3.16.7-ckt25-2+deb8u2.

We recommend that you upgrade your linux packages.
