This update for the Linux Kernel 3.12.39-47.1 fixes the following issues:
- CVE-2016-2384: A malicious USB device could cause a kernel crash in
the alsa usb-audio driver. (bsc#967773)
- CVE-2015-8812: A flaw was found in the CXGB3 kernel driver when
the network was considered congested. The kernel would incorrectly
misinterpret the congestion as an error condition and incorrectly
free/clean up the skb. When the device would then send the skb's queued,
these structures would be referenced and may panic the system or allow
an attacker to escalate privileges in a use-after-free scenario. (bsc#966683)
- CVE-2016-0774: A pipe buffer state corruption after unsuccessful atomic
read from pipe was fixed (bsc#964732).
- CVE-2015-8709: kernel/ptrace.c in the Linux kernel mishandled uid and
gid mappings, which allowed local users to gain privileges by establishing
a user namespace, waiting for a root process to enter that namespace
with an unsafe uid or gid, and then using the ptrace system call. NOTE:
the vendor states 'there is no kernel bug here.'

This kernel live patch for Linux Kernel 3.12.39-47.1 fixes security issues and bugs:
Security issues fixed:
- CVE-2015-8539: A negatively instantiated user key could have been used
by a local user to leverage privileges (bnc#958601).
- CVE-2015-6937: A NULL pointer dereference flaw was found in the Reliable
Datagram Sockets (RDS) implementation allowing a local user to cause
system DoS. A verification was missing that the underlying transport
exists when a connection was created. (bsc#953052)
- CVE-2015-7990: RDS: Verify the underlying transport exists before
creating a connection, preventing possible DoS (bsc#953052).
- CVE-2015-7872: Possible crash when trying to garbage collect an
uninstantiated keyring (bsc#951542).
- CVE-2015-2925: The prepend_path function in fs/dcache.c in the Linux
kernel did not properly handle rename actions inside a bind mount, which
allowed local users to bypass an intended container protection mechanism
by renaming a directory, related to a 'double-chroot attack (bnc#951625).
Non-security bugfix were also done:
- xfs: Fix lost direct IO write in the last block (bsc#954005).

This kernel live patch for Linux Kernel 3.12.39-47.1 fixes two security issues:
- CVE-2015-7613: A race condition in the IPC object implementation in
the Linux kernel allowed local users to gain privileges by triggering an
ipc_addid call that leads to uid and gid comparisons against uninitialized
data, related to msg.c, shm.c, and util.c. (bsc#948701 bsc#948536)
- CVE-2015-5707: Integer overflow in the sg_start_req function in
drivers/scsi/sg.c in the Linux kernel allowed local users to cause a
denial of service or possibly have unspecified other impact via a large
iov_count value in a write request.

This update contains a kernel live patch for the 3.12.39-47 SUSE Linux Enterprise
Server 12 Kernel, fixing following security issues.
- CVE-2015-3339: A race condition in the prepare_binprm function in
fs/exec.c in the Linux kernel allowed local users to gain privileges
by executing a setuid program at a time instant when a chown to root
is in progress, and the ownership is changed but the setuid bit is not
yet stripped. (bsc#939263 bsc#939044)
- CVE-2015-3636: The ping_unhash function in net/ipv4/ping.c in the
Linux kernel did not initialize a certain list data structure during an
unhash operation, which allowed local users to gain privileges or cause
a denial of service (use-after-free and system crash) by leveraging the
ability to make a SOCK_DGRAM socket system call for the IPPROTO_ICMP
or IPPROTO_ICMPV6 protocol, and then making a connect system call after
a disconnect. (bsc#939277)
- CVE-2015-5364/CVE-2015-5366: Two denial of service attacks via a flood
of UDP packets with invalid checksums were fixed that could be used
by remote attackers to delay execution. (bsc#939276)
- CVE-2015-1805: The (1) pipe_read and (2) pipe_write implementations in
fs/pipe.c in the Linux kernel did not properly consider the side effects
of failed __copy_to_user_inatomic and __copy_from_user_inatomic calls,
which allowed local users to cause a denial of service (system crash)
or possibly gain privileges via a crafted application, aka an 'I/O vector
array overrun.' (bsc#939270)
- CVE-2015-4700: A BPF Jit optimization flaw could allow local users
to panic the kernel. (bsc#939273)
- CVE-2015-3331: The __driver_rfc4106_decrypt function in
arch/x86/crypto/aesni-intel_glue.c in the Linux kernel did not properly
determine the memory locations used for encrypted data, which allowed
context-dependent attackers to cause a denial of service (buffer overflow
and system crash) or possibly execute arbitrary code by triggering a
crypto API call, as demonstrated by use of a libkcapi test program with
an AF_ALG(aead) socket. (bsc#939262)
- CVE-2014-8159: The InfiniBand (IB) implementation in the Linux kernel
did not properly restrict use of User Verbs for registration of memory
regions, which allowed local users to access arbitrary physical memory
locations, and consequently cause a denial of service (system crash)
or gain privileges, by leveraging permissions on a uverbs device under
/dev/infiniband/. (bsc#939241)CVSSUnscoredInsufficient evidenceSUSE-SU-2015:0658-1SUSE Linux Enterprisesuse · kernel-default&distro=SUSE Linux Enterprise Desktop 12 +16 moresuse kernel-default&distro=SUSE Linux Enterprise Desktop 12Security Update for Linux Kernel
The SUSE Linux Enterprise Server 12 kernel was updated to 3.12.39 to
receive various security and bugfixes.
Following security bugs were fixed:
- CVE-2015-0777: The XEN usb backend could leak information to the guest
system due to copying uninitialized memory.
- CVE-2015-2150: Xen and the Linux kernel did not properly restrict access
to PCI command registers, which might have allowed local guest users to
cause a denial of service (non-maskable interrupt and host crash) by
disabling the (1) memory or (2) I/O decoding for a PCI Express device
and then accessing the device, which triggers an Unsupported Request
(UR) response.
