Affected Products:

openSUSE 13.2

______________________________________________________________________________

 

An update that solves 12 vulnerabilities and has 19 fixes

is now available.

 

Description:

 

 

The openSUSE 13.2 kernel was updated to receive various security and

bugfixes.

 

The following security bugs were fixed:

 

- 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).

- CVE-2016-5195: A local privilege escalation using MAP_PRIVATE was fixed,

which is reportedly exploited in the wild (bsc#1004418).

- CVE-2016-8658: Stack-based buffer overflow in the

brcmf_cfg80211_start_ap function in

drivers/net/wireless/broadcom/brcm80211/brcmfmac/cfg80211.c in the Linux

kernel allowed local users to cause a denial of service (system crash)

or possibly have unspecified other impact via a long SSID Information

Element in a command to a Netlink socket (bnc#1004462).

- CVE-2016-7117: Use-after-free vulnerability in the __sys_recvmmsg

function in net/socket.c in the Linux kernel allowed remote attackers to

execute arbitrary code via vectors involving a recvmmsg system call that

is mishandled during error processing (bnc#1003077).

- CVE-2016-0823: The pagemap_open function in fs/proc/task_mmu.c in the

Linux kernel before 3.19.3, as used in Android 6.0.1 before 2016-03-01,

allowed local users to obtain sensitive physical-address information by

reading a pagemap file, aka Android internal bug 25739721 (bnc#994759).

- CVE-2016-7425: The arcmsr_iop_message_xfer function in

drivers/scsi/arcmsr/arcmsr_hba.c in the Linux kernel did not restrict a

certain length field, which allowed local users to gain privileges

or cause a denial of service (heap-based buffer overflow) via an

ARCMSR_MESSAGE_WRITE_WQBUFFER control code (bnc#999932).

- CVE-2016-6327: drivers/infiniband/ulp/srpt/ib_srpt.c in the Linux kernel

allowed local users to cause a denial of service (NULL pointer

dereference and system crash) by using an ABORT_TASK command to abort a

device write operation (bnc#994748).

- CVE-2016-6828: The tcp_check_send_head function in include/net/tcp.h in

the Linux kernel did not properly maintain certain SACK state after a

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

(tcp_xmit_retransmit_queue use-after-free and system crash) via a

crafted SACK option (bnc#994296).

- CVE-2016-5696: net/ipv4/tcp_input.c in the Linux kernel did not properly

determine the rate of challenge ACK segments, which made it easier for

man-in-the-middle attackers to hijack TCP sessions via a blind in-window

attack (bnc#989152)

- CVE-2016-6480: Race condition in the ioctl_send_fib function in

drivers/scsi/aacraid/commctrl.c in the Linux kernel allowed local users

to cause a denial of service (out-of-bounds access or system crash) by

changing a certain size value, aka a "double fetch" vulnerability

(bnc#991608).

- CVE-2015-7513: arch/x86/kvm/x86.c in the Linux kernel did not reset the

PIT counter values during state restoration, which allowed guest OS

users to cause a denial of service (divide-by-zero error and host OS

crash) via a zero value, related to the kvm_vm_ioctl_set_pit and

kvm_vm_ioctl_set_pit2 functions (bnc#960689).

- CVE-2016-1237: nfsd in the Linux kernel allowed local users to bypass

intended file-permission restrictions by setting a POSIX ACL, related to

nfs2acl.c, nfs3acl.c, and nfs4acl.c (bnc#986570).

 

The following non-security bugs were fixed:

 

- AF_VSOCK: Shrink the area influenced by prepare_to_wait (bsc#994520).

- xen: Fix refcnt regression in xen netback introduced by changes made for

bug#881008 (bnc#978094)

- Update patches.fixes/0002-nfsd-check-permissions-when-setting-ACLs.patch

(bsc#986570 CVE#2016-1237).

- Update patches.fixes/0001-posix_acl-Add-set_posix_acl.patch (bsc#986570

CVE#2016-1237).

- apparmor: fix change_hat not finding hat after policy replacement

(bsc#1000287).

- arm64: Honor __GFP_ZERO in dma allocations (bsc#1004045).

- arm64: __clear_user: handle exceptions on strb (bsc#994752).

- arm64: dma-mapping: always clear allocated buffers (bsc#1004045).

- arm64: perf: reject groups spanning multiple HW PMUs (bsc#1003931).

- blkfront: fix an error path memory leak (luckily none so far).

- blktap2: eliminate deadlock potential from shutdown path (bsc#909994).

- blktap2: eliminate race from deferred work queue handling (bsc#911687).

- btrfs: ensure that file descriptor used with subvol ioctls is a dir

(bsc#999600).

- cdc-acm: added sanity checking for probe() (bsc#993891).

- kaweth: fix firmware download (bsc#993890).

- kaweth: fix oops upon failed memory allocation (bsc#993890).

- netback: fix flipping mode (bsc#996664).

- netfront: linearize SKBs requiring too many slots (bsc#991247).

- nfsd: check permissions when setting ACLs (bsc#986570).

- posix_acl: Add set_posix_acl (bsc#986570).
