SUSE SLES11 Security Update : kernel (SUSE-SU-2016:2018-1)

This script is Copyright (C) 2016 Tenable Network Security, Inc.

Synopsis :

The remote SUSE host is missing one or more security updates.

Description :

The SUSE Linux Enterprise 11 SP4 kernel was updated to receive various
security and bugfixes. The following security bugs were fixed :

- CVE-2016-5829: Multiple heap-based buffer overflows in
the hiddev_ioctl_usage function in
drivers/hid/usbhid/hiddev.c in the Linux kernel allowed
local users to cause a denial of service or possibly
have unspecified other impact via a crafted (1)

- CVE-2016-4997: The compat IPT_SO_SET_REPLACE setsockopt
implementation in the netfilter subsystem in the Linux
kernel allowed local users to gain privileges or cause a
denial of service (memory corruption) by leveraging
in-container root access to provide a crafted offset
value that triggers an unintended decrement

- CVE-2016-4470: The key_reject_and_link function in
security/keys/key.c in the Linux kernel did not ensure
that a certain data structure is initialized, which
allowed local users to cause a denial of service (system
crash) via vectors involving a crafted keyctl request2
command (bnc#984755). The following non-security bugs
were fixed :

- RDMA/cxgb4: Configure 0B MRs to match HW implementation

- RDMA/cxgb4: Do not hang threads forever waiting on WR
replies (bsc#909589).

- RDMA/cxgb4: Fix locking issue in process_mpa_request

- RDMA/cxgb4: Handle NET_XMIT return codes (bsc#909589).

- RDMA/cxgb4: Increase epd buff size for debug interface

- RDMA/cxgb4: Limit MRs to less than 8GB for T4/T5 devices

- RDMA/cxgb4: Serialize CQ event upcalls with CQ
destruction (bsc#909589).

- RDMA/cxgb4: Wake up waiters after flushing the qp

- bridge: superfluous skb->nfct check in
br_nf_dev_queue_xmit (bsc#982544).

- iucv: call skb_linearize() when needed (bnc#979915,

- kabi: prevent spurious modversion changes after
bsc#982544 fix (bsc#982544).

- mm/swap.c: flush lru pvecs on compound page arrival

- mm: Fix DIF failures on ext3 filesystems (bsc#971030).

- net/qlge: Avoids recursive EEH error (bsc#954847).

- netfilter: bridge: Use __in6_dev_get rather than
in6_dev_get in br_validate_ipv6 (bsc#982544).

- netfilter: bridge: do not leak skb in error paths

- netfilter: bridge: forward IPv6 fragmented packets

- qeth: delete napi struct when removing a qeth device
(bnc#979915, LTC#143590).

- s390/mm: fix asce_bits handling with dynamic pagetable
levels (bnc#979915, LTC#141456).

- s390/pci: fix use after free in dma_init (bnc#979915,

- s390: fix test_fp_ctl inline assembly contraints
(bnc#979915, LTC#143138).

- sched/cputime: Fix clock_nanosleep()/clock_gettime()
inconsistency (bnc#988498).

- sched/cputime: Fix cpu_timer_sample_group() double
accounting (bnc#988498).

- sched: Provide update_curr callbacks for stop/idle
scheduling classes (bnc#988498).

- x86/mm/pat, /dev/mem: Remove superfluous error message
