Language:

Synopsis

The remote openSUSE host is missing a security update.

Description

The openSUSE Leap 42.2 kernel was updated to 4.4.36 to receive various security and bugfixes.

The following security bugs were fixed :

- CVE-2015-1350: The VFS subsystem in the Linux kernel 3.x provides an incomplete set of requirements for setattr operations that underspecifies removing extended privilege attributes, which allowed local users to cause a denial of service (capability stripping) via a failed invocation of a system call, as demonstrated by using chown to remove a capability from the ping or Wireshark dumpcap program (bnc#914939).

- 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-2016-7042: 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-2016-7913: 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-2016-7917: The nfnetlink_rcv_batch function in net/netfilter/nfnetlink.c in the Linux kernel did not check whether a batch message's length field is large enough, which allowed local users to obtain sensitive information from kernel memory or cause a denial of service (infinite loop or out-of-bounds read) by leveraging the CAP_NET_ADMIN capability (bnc#1010444).

- CVE-2016-8632: The tipc_msg_build function in net/tipc/msg.c in the Linux kernel did not validate the relationship between the minimum fragment length and the maximum packet size, which allowed local users to gain privileges or cause a denial of service (heap-based buffer overflow) by leveraging the CAP_NET_ADMIN capability (bnc#1008831).

- 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-2016-8666: The IP stack in the Linux kernel allowed remote attackers to cause a denial of service (stack consumption and panic) or possibly have unspecified other impact by triggering use of the GRO path for packets with tunnel stacking, as demonstrated by interleaved IPv4 headers and GRE headers, a related issue to CVE-2016-7039 (bnc#1001486).

- 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-2016-9555: 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-2016-9794: A use-after-free in alsa pcm could lead to crashes or allowed local users to potentially gain privileges (bsc#1013533).

- rpm/config.sh: Build against SP2 in the OBS as well

- rpm/constraints.in: increase disk for kernel-syzkaller The kernel-syzkaller build now consumes around 30G. This causes headache in factory where the package rebuilds over and over. Require 35G disk size to successfully build the flavor.

- rpm/kernel-binary.spec.in: Build the -base package unconditionally (bsc#1000118)

- rpm/kernel-binary.spec.in: Do not create KMPs with CONFIG_MODULES=n

- rpm/kernel-binary.spec.in: Only build -base and -extra with CONFIG_MODULES (bsc#1000118)

- tg3: Avoid NULL pointer dereference in tg3_io_error_detected() (bsc#963609 FATE#320143).

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

- Whitelist KVM KABI changes resulting from adding a hcall. caused by 5246adec59458b5d325b8e1462ea9ef3ead7f6ae powerpc/pseries: Use H_CLEAR_HPT to clear MMU hash table during kexec No problem is expected as result of changing KVM KABI so whitelisting for now. If we get some additional input from IBM we can back out the patch.

- writeback: initialize inode members that track writeback history (bsc#1012829).

- x86/mce/AMD: Read MSRs on the CPU allocating the threshold blocks (fate#320474, bsc#1013700).
