Description:
The SUSE Linux Enterprise 12 SP1 kernel was updated to 3.12.62 to receive various security and bugfixes.
The following security bugs were fixed: - CVE-2014-9904: The snd_compress_check_input function in sound/core/compress_offload.c in the ALSA subsystem in the Linux kernel did not properly check for an integer overflow, which allowed local users to cause a denial of service (insufficient memory allocation) or possibly have unspecified other impact via a crafted SNDRV_COMPRESS_SET_PARAMS ioctl call (bnc#986811). - CVE-2015-7833: The usbvision driver in the Linux kernel allowed physically proximate attackers to cause a denial of service (panic) via a nonzero bInterfaceNumber value in a USB device descriptor (bnc#950998). - CVE-2015-8551: The PCI backend driver in Xen, when running on an x86 system and using Linux as the driver domain, allowed local guest administrators to hit BUG conditions and cause a denial of service (NULL pointer dereference and host OS crash) by leveraging a system with access to a passed-through MSI or MSI-X capable physical PCI device and a crafted sequence of XEN_PCI_OP_* operations, aka "Linux pciback missing sanity checks (bnc#957990). - CVE-2015-8552: The PCI backend driver in Xen, when running on an x86 system and using Linux as the driver domain, allowed local guest administrators to generate a continuous stream of WARN messages and cause a denial of service (disk consumption) by leveraging a system with access to a passed-through MSI or MSI-X capable physical PCI device and XEN_PCI_OP_enable_msi operations, aka "Linux pciback missing sanity checks (bnc#957990). - CVE-2015-8845: The tm_reclaim_thread function in arch/powerpc/kernel/process.c in the Linux kernel on powerpc platforms did not ensure that TM suspend mode exists before proceeding with a tm_reclaim call, which allowed local users to cause a denial of service (TM Bad Thing exception and panic) via a crafted application (bnc#975533). -

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-2016-4997: 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 (bsc#986362). - 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 (bsc#986365). - CVE-2016-5244: The rds_inc_info_copy function in net/rds/recv.c in the Linux kernel did not initialize a certain structure member, which allowed remote attackers to obtain sensitive information from kernel stack memory by reading an RDS message (bnc#983213). - CVE-2016-5828: The start_thread function in arch/powerpc/kernel/process.c in the Linux kernel on powerpc platforms mishandled transactional state, which allowed local users to cause a denial of service (invalid process state or TM Bad Thing exception, and system crash) or possibly have unspecified other impact by starting and suspending a transaction an exec system call (bsc#986569). - CVE-2016-5829: Multiple heap-based buffer overflows in the hiddev_ioctl_usage function in drivers/hid/usbhid/hiddev.c in the Linux kernel allowed 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).
