The remote OracleVM system is missing necessary patches to address critical security updates : please see Oracle VM Security Advisory OVMSA-2016-0100 for details.

The openSUSE Leap 42.1 kernel was updated to 4.1.20 to receive various security and bugfixes.

The following security bugs were fixed :

  - CVE-2015-1339: A memory leak in cuse could be used to     exhaust kernel memory. (bsc#969356).

  - CVE-2015-7799: The slhc_init function in     drivers/net/slip/slhc.c in the Linux kernel did not     ensure that certain slot numbers are valid, which     allowed local users to cause a denial of service (NULL     pointer dereference and system crash) via a crafted     PPPIOCSMAXCID ioctl call (bnc#949936 951638).

  - CVE-2015-7872: The key_gc_unused_keys function in     security/keys/gc.c in the Linux kernel allowed local     users to cause a denial of service (OOPS) via crafted     keyctl commands (bnc#951440).

  - CVE-2015-7884: The vivid_fb_ioctl function in     drivers/media/platform/vivid/vivid-osd.c in the Linux     kernel did not initialize a certain structure member,     which allowed local users to obtain sensitive     information from kernel memory via a crafted application     (bnc#951626).

  - CVE-2015-8104: The KVM subsystem in the Linux kernel     allowed guest OS users to cause a denial of service     (host OS panic or hang) by triggering many #DB (aka     Debug) exceptions, related to svm.c (bnc#954404).

  - CVE-2015-8709: kernel/ptrace.c in the Linux kernel     mishandled uid and gid mappings, which allowed local     users to gain privileges by establishing a user     namespace, waiting for a root process to enter that     namespace with an unsafe uid or gid, and then using the     ptrace system call. NOTE: the vendor states 'there is no     kernel bug here (bnc#959709).

  - CVE-2015-8767: net/sctp/sm_sideeffect.c in the Linux     kernel did not properly manage the relationship between     a lock and a socket, which allowed local users to cause     a denial of service (deadlock) via a crafted sctp_accept     call. (bsc#961509)

  - CVE-2015-8785: The fuse_fill_write_pages function in     fs/fuse/file.c in the Linux kernel allowed local users     to cause a denial of service (infinite loop) via a     writev system call that triggers a zero length for the     first segment of an iov (bnc#963765).

  - CVE-2015-8787: The nf_nat_redirect_ipv4 function in     net/netfilter/nf_nat_redirect.c in the Linux kernel     allowed remote attackers to cause a denial of service     (NULL pointer dereference and system crash) or possibly     have unspecified other impact by sending certain IPv4     packets to an incompletely configured interface, a     related issue to CVE-2003-1604 (bnc#963931).

  - CVE-2015-8812: A flaw was found in the CXGB3 kernel     driver when the network was considered congested. The     kernel would incorrectly misinterpret the congestion as     an error condition and incorrectly free/clean up the     skb. When the device would then send the skb's queued,     these structures would be referenced and may panic the     system or allow an attacker to escalate privileges in a     use-after-free scenario. (bsc#966437).

  - CVE-2016-0723: Race condition in the tty_ioctl function     in drivers/tty/tty_io.c in the Linux kernel allowed     local users to obtain sensitive information from kernel     memory or cause a denial of service (use-after-free and     system crash) by making a TIOCGETD ioctl call during     processing of a TIOCSETD ioctl call (bnc#961500).

  - CVE-2016-2069: When Linux invalidated a paging structure     that is not in use locally, it could, in principle, race     against another CPU that is switching to a process that     uses the paging structure in question. (bsc#963767)

  - CVE-2016-2184: A malicious USB device could cause a     kernel crash in the alsa usb-audio driver. (bsc#971125)

  - CVE-2016-2383: Incorrect branch fixups for eBPF allow     arbitrary read of kernel memory. (bsc#966684)
