An update that solves 18 vulnerabilities and has 25 fixes
is now available.

Description:


The SUSE Linux Enterprise Server 11 SP2 LTSS kernel was updated to receive
various security and bugfixes.

The following security bugs were fixed:
- CVE-2015-5707: An integer overflow in the SCSI generic driver could be
potentially used by local attackers to crash the kernel or execute code.
- CVE-2015-2830: arch/x86/kernel/entry_64.S in the Linux kernel did not
prevent the TS_COMPAT flag from reaching a user-mode task, which might
have allowed local users to bypass the seccomp or audit protection
mechanism via a crafted application that uses the (1) fork or (2) close
system call, as demonstrated by an attack against seccomp before 3.16
(bnc#926240).
- CVE-2015-0777: drivers/xen/usbback/usbback.c in the Linux kernel allowed
guest OS users to obtain sensitive information from uninitialized
locations in host OS kernel memory via unspecified vectors (bnc#917830).
- 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 (bnc#919463).
- CVE-2015-5364: A remote denial of service (hang) via UDP flood with
incorrect package checksums was fixed. (bsc#936831).
- CVE-2015-5366: A remote denial of service (unexpected error returns) via
UDP flood with incorrect package checksums was fixed. (bsc#936831).
- CVE-2015-1420: CVE-2015-1420: Race condition in the handle_to_path
function in fs/fhandle.c in the Linux kernel allowed local users to
bypass intended size restrictions and trigger read operations on
additional memory locations by changing the handle_bytes value of a file
handle during the execution of this function (bnc#915517).
- CVE-2015-4700: A local user could have created a bad instruction in the
JIT processed BPF code, leading to a kernel crash (bnc#935705).
- 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" (bnc#933429).
- 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 (bnc#927257).
- CVE-2015-2922: The ndisc_router_discovery function in net/ipv6/ndisc.c
in the Neighbor Discovery (ND) protocol implementation in the IPv6 stack
in the Linux kernel allowed remote attackers to reconfigure a hop-limit
setting via a small hop_limit value in a Router Advertisement (RA)
message (bnc#922583).
- CVE-2015-2041: net/llc/sysctl_net_llc.c in the Linux kernel used an
incorrect data type in a sysctl table, which allowed local users to
obtain potentially sensitive information from kernel memory or possibly
have unspecified other impact by accessing a sysctl entry (bnc#919007).
- 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 (bnc#929525).
- CVE-2014-8086: Race condition in the ext4_file_write_iter function in
fs/ext4/file.c in the Linux kernel allowed local users to cause a denial
of service (file unavailability) via a combination of a write action and
an F_SETFL fcntl operation for the O_DIRECT flag (bnc#900881).
- 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/ (bnc#914742).
- CVE-2014-9683: Off-by-one error in the ecryptfs_decode_from_filename
function in fs/ecryptfs/crypto.c in the eCryptfs subsystem in the Linux
kernel allowed local users to cause a denial of service (buffer overflow
and system crash) or possibly gain privileges via a crafted filename
(bnc#918333).
- CVE-2015-2042: net/rds/sysctl.c in the Linux kernel used an incorrect
data type in a sysctl table, which allowed local users to obtain
potentially sensitive information from kernel memory or possibly have
unspecified other impact by accessing a sysctl entry (bnc#919018).
- CVE-2015-1421: Use-after-free vulnerability in the sctp_assoc_update
function in net/sctp/associola.c in the Linux kernel allowed remote
attackers to cause a denial of service (slab corruption and panic) or
possibly have unspecified other impact by triggering an INIT collision
that leads to improper handling of shared-key data (bnc#915577).
