Affected Products:

openSUSE Leap 42.1

______________________________________________________________________________

 

An update that solves 16 vulnerabilities and has 12 fixes

is now available.

 

Description:

 

 

 

The openSUSE Leap 42.1 kernel was updated to 4.1.36 to receive various

security and bugfixes.

 

The following security bugs were fixed:

 

- CVE-2016-8655: A race condition in the af_packet packet_set_ring

function could be used by local attackers to crash the kernel or gain

privileges (bsc#1012754).

- CVE-2016-9794: A use-after-free in ALSA pcm could lead to crashes or

allowed local users to potentially gain privileges (bsc#1013533).

- CVE-2015-8962: Double free vulnerability in the sg_common_write function

in drivers/scsi/sg.c in the Linux kernel allowed local users to gain

privileges or cause a denial of service (memory corruption and system

crash) by detaching a device during an SG_IO ioctl call (bnc#1010501).

- CVE-2016-9178: The __get_user_asm_ex macro in

arch/x86/include/asm/uaccess.h in the Linux kernel did not initialize a

certain integer variable, which allowed local users to obtain sensitive

information from kernel stack memory by triggering failure of a

get_user_ex call (bnc#1008650).

- CVE-2016-7913: The xc2028_set_config function in

drivers/media/tuners/tuner-xc2028.c in the Linux kernel allowed local

users to gain privileges or cause a denial of service (use-after-free)

via vectors involving omission of the firmware name from a certain data

structure (bnc#1010478).

- CVE-2016-9555: The sctp_sf_ootb function in net/sctp/sm_statefuns.c in

the Linux kernel lacks chunk-length checking for the first chunk, which

allowed remote attackers to cause a denial of service (out-of-bounds

slab access) or possibly have unspecified other impact via crafted SCTP

data (bnc#1011685).

- CVE-2015-8963: Race condition in kernel/events/core.c in the Linux

kernel allowed local users to gain privileges or cause a denial of

service (use-after-free) by leveraging incorrect handling of an swevent

data structure during a CPU unplug operation (bnc#1010502).

- CVE-2015-8964: The tty_set_termios_ldisc function in

drivers/tty/tty_ldisc.c in the Linux kernel allowed local users to

obtain sensitive information from kernel memory by reading a tty data

structure (bnc#1010507).

- CVE-2016-8646: The hash_accept function in crypto/algif_hash.c in the

Linux kernel allowed local users to cause a denial of service (OOPS) by

attempting to trigger use of in-kernel hash algorithms for a socket that

has received zero bytes of data (bnc#1010150).

- CVE-2016-8633: drivers/firewire/net.c in the Linux kernel in certain

unusual hardware configurations, allowed remote attackers to execute

arbitrary code via crafted fragmented packets (bnc#1008833).

- CVE-2016-8630: The x86_decode_insn function in arch/x86/kvm/emulate.c in

the Linux kernel, when KVM is enabled, allowed local users to cause a

denial of service (host OS crash) via a certain use of a ModR/M byte in

an undefined instruction (bnc#1009222).

- CVE-2016-9083: drivers/vfio/pci/vfio_pci.c in the Linux kernel allowed

local users to bypass integer overflow checks, and cause a denial of

service (memory corruption) or have unspecified other impact, by

leveraging access to a vfio PCI device file for a VFIO_DEVICE_SET_IRQS

ioctl call, aka a "state machine confusion bug (bnc#1007197).

- CVE-2016-9084: drivers/vfio/pci/vfio_pci_intrs.c in the Linux kernel

misuses the kzalloc function, which allowed local users to cause a

denial of service (integer overflow) or have unspecified other impact by

leveraging access to a vfio PCI device file (bnc#1007197).

- CVE-2016-7042: The proc_keys_show function in security/keys/proc.c in

the Linux kernel through 4.8.2, when the GNU Compiler Collection (gcc)

stack protector is enabled, uses an incorrect buffer size for certain

timeout data, which allowed local users to cause a denial of service

(stack memory corruption and panic) by reading the /proc/keys file

(bnc#1004517).

- CVE-2016-7097: The filesystem implementation in the Linux kernel

preserves the setgid bit during a setxattr call, which allowed local

users to gain group privileges by leveraging the existence of a setgid

program with restrictions on execute permissions (bnc#995968).

- CVE-2015-8956: The rfcomm_sock_bind function in

net/bluetooth/rfcomm/sock.c in the Linux kernel allowed local users to

obtain sensitive information or cause a denial of service (NULL pointer

dereference) via vectors involving a bind system call on a Bluetooth

RFCOMM socket (bnc#1003925).

 

The following non-security bugs were fixed:

 

- ata: ahci_xgene: dereferencing uninitialized pointer in probe

(bsc#1006580).

- blacklist.conf: add some commits (bsc#1006580)

- bna: Add synchronization for tx ring (bsc#993739).

- bonding: set carrier off for devices created through netlink

(bsc#999577).

- btrfs: deal with duplicates during extent_map insertion in

btrfs_get_extent (bsc#1001171).

- btrfs: deal with existing encompassing extent map in btrfs_get_extent()

(bsc#1001171).

- btrfs: fix extent tree corruption due to relocation (bsc#990384).

- btrfs: fix races on root_log_ctx lists (bsc#1007653).

- ext4: fix data exposure after a crash (bsc#1012876).

- ext4: fix reference counting bug on block allocation error (bsc#1012876).

- gre: Disable segmentation offloads w/ CSUM and we are encapsulated via

FOU (bsc#1001486).

- gro: Allow tunnel stacking in the case of FOU/GUE (bsc#1001486).

- ipv6: send NEWLINK on RA managed/otherconf changes (bsc#934067).

- ipv6: send only one NEWLINK when RA causes changes (bsc#934067).

- isofs: Do not return EACCES for unknown filesystems (bsc#1012876).

- jbd2: fix checkpoint list cleanup (bsc#1012876).

- jbd2: Fix unreclaimed pages after truncate in data=journal mode

(bsc#1010909).

- locking/static_key: Fix concurrent static_key_slow_inc() (bsc#1006580).

- mmc: Fix kabi breakage of mmc-block in 4.1.36 (stable-4.1.36).

- posix_acl: Added fix for f2fs.

- Revert "kbuild: add -fno-PIE" (stable-4.1.36).

- Revert "x86/mm: Expand the exception table logic to allow new handling

options" (stable-4.1.36).

- tunnels: Remove encapsulation offloads on decap (bsc#1001486).

- usbhid: add ATEN CS962 to list of quirky devices (bsc#1007615).
