An update that solves 8 vulnerabilities and has 7 fixes is
now available.

Description:

The openSUSE Leap 42.1 kernel was updated to receive various security and
bugfixes.

The following security bugs were fixed:

– CVE-2017-7618: crypto/ahash.c in the Linux kernel allowed attackers to
cause a denial of service (API operation calling its own callback, and
infinite recursion) by triggering EBUSY on a full queue (bnc#1033340).
– CVE-2016-10318: A missing authorization check in the
fscrypt_process_policy function in fs/crypto/policy.c in the ext4 and
f2fs filesystem encryption support in the Linux kernel allowed a user to
assign an encryption policy to a directory owned by a different user,
potentially creating a denial of service (bnc#1032435).
– CVE-2017-7616: Incorrect error handling in the set_mempolicy and mbind
compat syscalls in mm/mempolicy.c in the Linux kernel allowed local
users to obtain sensitive information from uninitialized stack data by
triggering failure of a certain bitmap operation (bnc#1033336).
– CVE-2017-7308: The packet_set_ring function in net/packet/af_packet.c in
the Linux kernel did not properly validate certain block-size data,
which allowed local users to cause a denial of service (overflow) or
possibly have unspecified other impact via crafted system calls
(bnc#1031579).
– CVE-2017-2671: The ping_unhash function in net/ipv4/ping.c in the Linux
kernel is too late in obtaining a certain lock and consequently cannot
ensure that disconnect function calls are safe, which allowed local
users to cause a denial of service (panic) by leveraging access to the
protocol value of IPPROTO_ICMP in a socket system call (bnc#1031003).
– CVE-2017-7294: The vmw_surface_define_ioctl function in
drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux kernel did not
validate addition of certain levels data, which allowed local users to
trigger an integer overflow and out-of-bounds write, and cause a denial
of service (system hang or crash) or possibly gain privileges, via a
crafted ioctl call for a /dev/dri/renderD* device (bnc#1031440).
– CVE-2017-7261: The vmw_surface_define_ioctl function in
drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux kernel did not
check for a zero value of certain levels data, which allowed local users
to cause a denial of service (ZERO_SIZE_PTR dereference, and GPF and
possibly panic) via a crafted ioctl call for a /dev/dri/renderD* device
(bnc#1031052).
– CVE-2017-7187: The sg_ioctl function in drivers/scsi/sg.c in the Linux
kernel allowed local users to cause a denial of service (stack-based
buffer overflow) or possibly have unspecified other impact via a large
command size in an SG_NEXT_CMD_LEN ioctl call, leading to out-of-bounds
write access in the sg_write function (bnc#1030213).

The following non-security bugs were fixed:

– ata: ahci_xgene: free structure returned by acpi_get_object_info()
(bsc#1033518).
– doc/README.SUSE: update links to KMP manual
– ext4: do not perform data journaling when data is encrypted
(bsc#1012876).
– ext4: fix use-after-iput when fscrypt contexts are inconsistent
(bsc#1012829).
– ext4: mark inode dirty after converting inline directory (bsc#1012876).
– ext4: reject inodes with negative size (bsc#1012876).
– fs, seqfile: always allow oom killer (bsc#1012876).
– ipv6: make ECMP route replacement less greedy (bsc#930399).
– l2tp: hold tunnel socket when handling control frames in l2tp_ip and
l2tp_ip6 (bsc#1028415).
– mm: filemap: do not plant shadow entries without radix tree node
(bsc#1012876).
– netfilter: allow logging from non-init namespaces (bsc#970083).
– nfsd4: minor NFSv2/v3 write decoding cleanup (bsc#1034670 CVE#2017-7645).
– nfsd: check for oversized NFSv2/v3 arguments (bsc#1034670 CVE#2017-7645).
– nfsd: stricter decoding of write-like NFSv2/v3 ops (bsc#1034670
CVE#2017-7645).
