Описание

The SUSE Linux Enterprise 11 SP3 LTSS kernel was updated to receive various security and bugfixes.

The following security bugs were fixed:

• CVE-2016-3955: The usbip_recv_xbuff function in drivers/usb/usbip/usbip_common.c in the Linux kernel allowed remote attackers to cause a denial of service (out-of-bounds write) or possibly have unspecified other impact via a crafted length value in a USB/IP packet (bnc#975945).
• CVE-2016-4998: The IPT_SO_SET_REPLACE setsockopt implementation in the netfilter subsystem in the Linux kernel allowed local users to cause a denial of service (out-of-bounds read) or possibly obtain sensitive information from kernel heap memory by leveraging in-container root access to provide a crafted offset value that leads to crossing a ruleset blob boundary (bnc#986365).
• 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-2013-4312: The Linux kernel allowed local users to bypass file-descriptor limits and cause a denial of service (memory consumption) by sending each descriptor over a UNIX socket before closing it, related to net/unix/af_unix.c and net/unix/garbage.c (bnc#839104).
• 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 (bnc#986362).
• CVE-2016-5829: Multiple heap-based buffer overflows in the hiddev_ioctl_usage function in drivers/hid/usbhid/hiddev.c in the Linux kernel allow local users to cause a denial of service or possibly have unspecified other impact via a crafted (1) HIDIOCGUSAGES or (2) HIDIOCSUSAGES ioctl call (bnc#986572).

• CVE-2016-4805: Use-after-free vulnerability in drivers/net/ppp/ppp_generic.c in the Linux kernel allowed local users to cause a denial of service (memory corruption and system crash, or spinlock) or possibly have unspecified other impact by removing a network namespace, related to the ppp_register_net_channel and ppp_unregister_channel functions (bnc#980371).
• CVE-2016-0758: Integer overflow in lib/asn1_decoder.c in the Linux kernel allowed local users to gain privileges via crafted ASN.1 data (bnc#979867).

• CVE-2016-4482: The proc_connectinfo function in drivers/usb/core/devio.c in the Linux kernel did not initialize a certain data structure, which allowed local users to obtain sensitive information from kernel stack memory via a crafted USBDEVFS_CONNECTINFO ioctl call (bnc#978401).
• CVE-2016-4565: The InfiniBand (aka IB) stack in the Linux kernel incorrectly relies on the write system call, which allowed local users to cause a denial of service (kernel memory write operation) or possibly have unspecified other impact via a uAPI interface (bnc#979548).
• CVE-2016-2053: The asn1_ber_decoder function in lib/asn1_decoder.c in the Linux kernel allowed attackers to cause a denial of service (panic) via an ASN.1 BER file that lacks a public key, leading to mishandling by the public_key_verify_signature function in crypto/asymmetric_keys/public_key.c (bnc#963762).
• CVE-2016-4485: The llc_cmsg_rcv function in net/llc/af_llc.c in the Linux kernel did not initialize a certain data structure, which allowed attackers to obtain sensitive information from kernel stack memory by reading a message (bnc#978821).
• CVE-2016-4578: sound/core/timer.c in the Linux kernel did not initialize certain r1 data structures, which allowed local users to obtain sensitive information from kernel stack memory via crafted use of the ALSA timer interface, related to the (1) snd_timer_user_ccallback and (2) snd_timer_user_tinterrupt functions (bnc#979879).
• CVE-2016-4569: The snd_timer_user_params function in sound/core/timer.c in the Linux kernel did not initialize a certain data structure, which allowed local users to obtain sensitive information from kernel stack memory via crafted use of the ALSA timer interface (bnc#979213).
• CVE-2016-4486: The rtnl_fill_link_ifmap function in net/core/rtnetlink.c in the Linux kernel did not initialize a certain data structure, which allowed local users to obtain sensitive information from kernel stack memory by reading a Netlink message (bnc#978822).

• 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. (bsc#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. (bsc#991608)
