The remote Redhat Enterprise Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2015:1272 advisory.

    The kernel packages contain the Linux kernel, the core of any Linux     operating system.

    * A flaw was found in the way Linux kernel's Transparent Huge Pages (THP)     implementation handled non-huge page migration. A local, unprivileged user     could use this flaw to crash the kernel by migrating transparent hugepages.
    (CVE-2014-3940, Moderate)

    * A buffer overflow flaw was found in the way the Linux kernel's eCryptfs     implementation decoded encrypted file names. A local, unprivileged user     could use this flaw to crash the system or, potentially, escalate their     privileges on the system. (CVE-2014-9683, Moderate)

    * A race condition flaw was found between the chown and execve system     calls. When changing the owner of a setuid user binary to root, the race     condition could momentarily make the binary setuid root. A local,     unprivileged user could potentially use this flaw to escalate their     privileges on the system. (CVE-2015-3339, Moderate)

    * Multiple out-of-bounds write flaws were found in the way the Cherry     Cymotion keyboard driver, KYE/Genius device drivers, Logitech device     drivers, Monterey Genius KB29E keyboard driver, Petalynx Maxter remote     control driver, and Sunplus wireless desktop driver handled HID reports     with an invalid report descriptor size. An attacker with physical access to     the system could use either of these flaws to write data past an allocated     memory buffer. (CVE-2014-3184, Low)

    * An information leak flaw was found in the way the Linux kernel's Advanced     Linux Sound Architecture (ALSA) implementation handled access of the user     control's state. A local, privileged user could use this flaw to leak     kernel memory to user space. (CVE-2014-4652, Low)

    * It was found that the espfix functionality could be bypassed by     installing a 16-bit RW data segment into GDT instead of LDT (which espfix     checks), and using that segment on the stack. A local, unprivileged user     could potentially use this flaw to leak kernel stack addresses.
    (CVE-2014-8133, Low)

    * An information leak flaw was found in the Linux kernel's IEEE 802.11     wireless networking implementation. When software encryption was used, a     remote attacker could use this flaw to leak up to 8 bytes of plaintext.
    (CVE-2014-8709, Low)

    * It was found that the Linux kernel KVM subsystem's sysenter instruction     emulation was not sufficient. An unprivileged guest user could use this     flaw to escalate their privileges by tricking the hypervisor to emulate a     SYSENTER instruction in 16-bit mode, if the guest OS did not initialize the     SYSENTER model-specific registers (MSRs). Note: Certified guest operating     systems for Red Hat Enterprise Linux with KVM do initialize the SYSENTER     MSRs and are thus not vulnerable to this issue when running on a KVM     hypervisor. (CVE-2015-0239, Low)

According to the versions of the kernel packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities :

  - A flaw was found in the way the Linux kernel's perf     subsystem retrieved userlevel stack traces on PowerPC     systems. A local, unprivileged user could use this flaw     to cause a denial of service on the system by creating     a special stack layout that would force the     perf_callchain_user_64() function into an infinite     loop.(CVE-2015-6526i1/4%0

  - A vulnerability was found in the Linux kernel. Payloads     of NM entries are not supposed to contain NUL. When     such entry is processed, only the part prior to the     first NUL goes into the concatenation (i.e. the     directory entry name being encoded by a bunch of NM     entries). The process stops when the amount collected     so far + the claimed amount in the current NM entry     exceed 254. However, the value returned as the total     length is the sum of *claimed* sizes, not the actual     amount collected. And that's what will be passed to     readdir() callback as the name length - 8Kb
    __copy_to_user() from a buffer allocated by
    __get_free_page().(CVE-2016-4913i1/4%0

  - The perf_trace_event_perm function in     kernel/trace/trace_event_perf.c in the Linux kernel     before 3.12.2 does not properly restrict access to the     perf subsystem, which allows local users to enable     function tracing via a crafted     application.(CVE-2013-2930i1/4%0

  - The mincore() implementation in mm/mincore.c in the     Linux kernel through 4.19.13 allowed local attackers to     observe page cache access patterns of other processes     on the same system, potentially allowing sniffing of     secret information. (Fixing this affects the output of     the fincore program.) Limited remote exploitation may     be possible, as demonstrated by latency differences in     accessing public files from an Apache HTTP     Server.(CVE-2019-5489i1/4%0

  - It was found that the espfix functionality could be     bypassed by installing a 16-bit RW data segment into     GDT instead of LDT (which espfix checks), and using     that segment on the stack. A local, unprivileged user     could potentially use this flaw to leak kernel stack     addresses.(CVE-2014-8133i1/4%0

  - An issue was discovered in the btrfs filesystem code in     the Linux kernel. An out-of-bounds access is possible     in write_extent_buffer() when mounting and operating a     crafted btrfs image due to a lack of verification at     mount time within the btrfs_read_block_groups() in     fs/btrfs/extent-tree.c function. This could lead to a     system crash and a denial of service.(CVE-2018-14610i1/4%0

  - kernel/bpf/verifier.c in the Linux kernel through     4.14.8 mishandles states_equal comparisons between the     pointer data type and the UNKNOWN_VALUE data type,     which allows local users to obtain potentially     sensitive address information, aka a 'pointer     leak.'(CVE-2017-17864i1/4%0

  - drivers/hid/hid-lenovo-tpkbd.c in the Human Interface     Device (HID) subsystem in the Linux kernel through     3.11, when CONFIG_HID_LENOVO_TPKBD is enabled, allows     physically proximate attackers to cause a denial of     service (heap-based out-of-bounds write) via a crafted     device.(CVE-2013-2894i1/4%0

  - Memory leak in the sas_smp_get_phy_events function in     drivers/scsi/libsas/sas_expander.c in the Linux kernel     allows local users to cause a denial of service (kernel     memory exhaustion) via multiple read accesses to files     in the /sys/class/sas_phy directory.(CVE-2018-7757i1/4%0

  - It was found that the original fix for CVE-2016-6786     was incomplete. There exist a race between two     concurrent sys_perf_event_open() calls when both try     and move the same pre-existing software group into a     hardware context.(CVE-2017-6001i1/4%0

  - In the Linux kernel before 4.20.12,     net/ipv4/netfilter/nf_nat_snmp_basic_main.c in the SNMP     NAT module has insufficient ASN.1 length checks (aka an     array index error), making out-of-bounds read and write     operations possible, leading to an OOPS or local     privilege escalation. This affects snmp_version and     snmp_helper.(CVE-2019-9162i1/4%0

  - An information leak flaw was found in the way the Linux     kernel's Advanced Linux Sound Architecture (ALSA)     implementation handled access of the user control's     state. A local, privileged user could use this flaw to     leak kernel memory to user space.(CVE-2014-4652i1/4%0

  - A flaw was found that the vfs_rename() function did not     detect hard links on overlayfs. A local, unprivileged     user could use the rename syscall on overlayfs on top     of xfs to crash the system.(CVE-2016-6198i1/4%0

  - It was found that when file permissions were modified     via chmod and the user modifying them was not in the     owning group or capable of CAP_FSETID, the setgid bit     would be cleared. Setting a POSIX ACL via setxattr sets     the file permissions as well as the new ACL, but     doesn't clear the setgid bit in a similar way. This     could allow a local user to gain group privileges via     certain setgid applications.(CVE-2016-7097i1/4%0

  - A flaw was found in the way the Linux kernel's Crypto     subsystem handled automatic loading of kernel modules.
    A local user could use this flaw to load any installed     kernel module, and thus increase the attack surface of     the running kernel.(CVE-2014-9644i1/4%0

  - An arbitrary memory r/w access issue was found in the     Linux kernel compiled with the eBPF bpf(2) system call     (CONFIG_BPF_SYSCALL) support. The issue could occur due     to calculation errors in the eBPF verifier module,     triggered by user supplied malicious BPF program. An     unprivileged user could use this flaw to escalate their     privileges on a system. Setting parameter     'kernel.unprivileged_bpf_disabled=1' prevents such     privilege escalation by restricting access to bpf(2)     call.(CVE-2017-16995i1/4%0

  - A flaw was found in the implementation of associative     arrays where the add_key systemcall and KEYCTL_UPDATE     operations allowed for a NULL payload with a nonzero     length. When accessing the payload within this length     parameters value, an unprivileged user could trivially     cause a NULL pointer dereference (kernel     oops).(CVE-2017-15274i1/4%0

  - A flaw was found in the Linux kernel's keyring handling     code: the key_reject_and_link() function could be     forced to free an arbitrary memory block. An attacker     could use this flaw to trigger a use-after-free     condition on the system, potentially allowing for     privilege escalation.(CVE-2016-4470i1/4%0

  - A flaw was found in the way certain interfaces of the     Linux kernel's Infiniband subsystem used write() as     bi-directional ioctl() replacement, which could lead to     insufficient memory security checks when being invoked     using the splice() system call. A local unprivileged     user on a system with either Infiniband hardware     present or RDMA Userspace Connection Manager Access     module explicitly loaded, could use this flaw to     escalate their privileges on the     system.(CVE-2016-4565i1/4%0

  - It was found that the Linux kernel's IPv6 network stack     did not properly validate the value of the MTU variable     when it was set. A remote attacker could potentially     use this flaw to disrupt a target system's networking     (packet loss) by setting an invalid MTU value, for     example, via a NetworkManager daemon that is processing     router advertisement packets running on the target     system.(CVE-2015-8215i1/4%0

* An information leak flaw in the Linux kernel's ALSA implementation could allow a local, privileged user to leak kernel memory to user space. (CVE-2014-4652, Low)

The SUSE Linux Enterprise Server 11 SP2 LTSS received a roll up update to fix several security and non-security issues.

The following security issues have been fixed :

  - CVE-2014-0055: The get_rx_bufs function in     drivers/vhost/net.c in the vhost-net subsystem in the     Linux kernel package before 2.6.32-431.11.2 on Red Hat     Enterprise Linux (RHEL) 6 does not properly handle     vhost_get_vq_desc errors, which allows guest OS users to     cause a denial of service (host OS crash) via     unspecified vectors. (bnc#870173)

  - CVE-2014-0077: drivers/vhost/net.c in the Linux kernel     before 3.13.10, when mergeable buffers are disabled,     does not properly validate packet lengths, which allows     guest OS users to cause a denial of service (memory     corruption and host OS crash) or possibly gain     privileges on the host OS via crafted packets, related     to the handle_rx and get_rx_bufs functions. (bnc#870576)

  - CVE-2014-1739: The media_device_enum_entities function     in drivers/media/media-device.c in the Linux kernel     before 3.14.6 does not initialize a certain data     structure, which allows local users to obtain sensitive     information from kernel memory by leveraging /dev/media0     read access for a MEDIA_IOC_ENUM_ENTITIES ioctl call.
    (bnc#882804)

  - CVE-2014-2706: Race condition in the mac80211 subsystem     in the Linux kernel before 3.13.7 allows remote     attackers to cause a denial of service (system crash)     via network traffic that improperly interacts with the     WLAN_STA_PS_STA state (aka power-save mode), related to     sta_info.c and tx.c. (bnc#871797)

  - CVE-2014-2851: Integer overflow in the ping_init_sock     function in net/ipv4/ping.c in the Linux kernel through     3.14.1 allows local users to cause a denial of service     (use-after-free and system crash) or possibly gain     privileges via a crafted application that leverages an     improperly managed reference counter. (bnc#873374)

NOTE:
    the affected code was moved to the __skb_get_nlattr and
    __skb_get_nlattr_nest functions before the vulnerability     was announced. (bnc#877257)

  - CVE-2014-3145: The BPF_S_ANC_NLATTR_NEST extension     implementation in the sk_run_filter function in     net/core/filter.c in the Linux kernel through 3.14.3     uses the reverse order in a certain subtraction, which     allows local users to cause a denial of service     (over-read and system crash) via crafted BPF     instructions. NOTE: the affected code was moved to the
    __skb_get_nlattr_nest function before the vulnerability     was announced. (bnc#877257)

  - CVE-2014-3917: kernel/auditsc.c in the Linux kernel     through 3.14.5, when CONFIG_AUDITSYSCALL is enabled with     certain syscall rules, allows local users to obtain     potentially sensitive single-bit values from kernel     memory or cause a denial of service (OOPS) via a large     value of a syscall number. (bnc#880484)

  - CVE-2014-4508: arch/x86/kernel/entry_32.S in the Linux     kernel through 3.15.1 on 32-bit x86 platforms, when     syscall auditing is enabled and the sep CPU feature flag     is set, allows local users to cause a denial of service     (OOPS and system crash) via an invalid syscall number,     as demonstrated by number 1000. (bnc#883724)

  - CVE-2014-4652: Race condition in the tlv handler     functionality in the snd_ctl_elem_user_tlv function in     sound/core/control.c in the ALSA control implementation     in the Linux kernel before 3.15.2 allows local users to     obtain sensitive information from kernel memory by     leveraging /dev/snd/controlCX access. (bnc#883795)

  - CVE-2014-4653: sound/core/control.c in the ALSA control     implementation in the Linux kernel before 3.15.2 does     not ensure possession of a read/write lock, which allows     local users to cause a denial of service     (use-after-free) and obtain sensitive information from     kernel memory by leveraging /dev/snd/controlCX access.
    (bnc#883795)

  - CVE-2014-4654: The snd_ctl_elem_add function in     sound/core/control.c in the ALSA control implementation     in the Linux kernel before 3.15.2 does not check     authorization for SNDRV_CTL_IOCTL_ELEM_REPLACE commands,     which allows local users to remove kernel controls and     cause a denial of service (use-after-free and system     crash) by leveraging /dev/snd/controlCX access for an     ioctl call. (bnc#883795)

  - CVE-2014-4655: The snd_ctl_elem_add function in     sound/core/control.c in the ALSA control implementation     in the Linux kernel before 3.15.2 does not properly     maintain the user_ctl_count value, which allows local     users to cause a denial of service (integer overflow and     limit bypass) by leveraging /dev/snd/controlCX access     for a large number of SNDRV_CTL_IOCTL_ELEM_REPLACE ioctl     calls. (bnc#883795)

  - CVE-2014-4656: Multiple integer overflows in     sound/core/control.c in the ALSA control implementation     in the Linux kernel before 3.15.2 allow local users to     cause a denial of service by leveraging     /dev/snd/controlCX access, related to (1) index values     in the snd_ctl_add function and (2) numid values in the     snd_ctl_remove_numid_conflict function. (bnc#883795)

  - CVE-2014-4667: The sctp_association_free function in     net/sctp/associola.c in the Linux kernel before 3.15.2     does not properly manage a certain backlog value, which     allows remote attackers to cause a denial of service     (socket outage) via a crafted SCTP packet. (bnc#885422)

  - CVE-2014-4699: The Linux kernel before 3.15.4 on Intel     processors does not properly restrict use of a     non-canonical value for the saved RIP address in the     case of a system call that does not use IRET, which     allows local users to leverage a race condition and gain     privileges, or cause a denial of service (double fault),     via a crafted application that makes ptrace and fork     system calls. (bnc#885725)

  - CVE-2014-5077: The sctp_assoc_update function in     net/sctp/associola.c in the Linux kernel through 3.15.8,     when SCTP authentication is enabled, allows remote     attackers to cause a denial of service (NULL pointer     dereference and OOPS) by starting to establish an     association between two endpoints immediately after an     exchange of INIT and INIT ACK chunks to establish an     earlier association between these endpoints in the     opposite direction. (bnc#889173)

  - CVE-2013-4299: Interpretation conflict in     drivers/md/dm-snap-persistent.c in the Linux kernel     through 3.11.6 allows remote authenticated users to     obtain sensitive information or modify data via a     crafted mapping to a snapshot block device. (bnc#846404)

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

* A flaw was found in the way Linux kernel's Transparent Huge Pages (THP) implementation handled non-huge page migration. A local, unprivileged user could use this flaw to crash the kernel by migrating transparent hugepages. (CVE-2014-3940, Moderate)

* A buffer overflow flaw was found in the way the Linux kernel's eCryptfs implementation decoded encrypted file names. A local, unprivileged user could use this flaw to crash the system or, potentially, escalate their privileges on the system. (CVE-2014-9683, Moderate)

* A race condition flaw was found between the chown and execve system calls. When changing the owner of a setuid user binary to root, the race condition could momentarily make the binary setuid root. A local, unprivileged user could potentially use this flaw to escalate their privileges on the system. (CVE-2015-3339, Moderate)

* Multiple out-of-bounds write flaws were found in the way the Cherry Cymotion keyboard driver, KYE/Genius device drivers, Logitech device drivers, Monterey Genius KB29E keyboard driver, Petalynx Maxter remote control driver, and Sunplus wireless desktop driver handled HID reports with an invalid report descriptor size. An attacker with physical access to the system could use either of these flaws to write data past an allocated memory buffer. (CVE-2014-3184, Low)

* An information leak flaw was found in the way the Linux kernel's Advanced Linux Sound Architecture (ALSA) implementation handled access of the user control's state. A local, privileged user could use this flaw to leak kernel memory to user space. (CVE-2014-4652, Low)

* It was found that the espfix functionality could be bypassed by installing a 16-bit RW data segment into GDT instead of LDT (which espfix checks), and using that segment on the stack. A local, unprivileged user could potentially use this flaw to leak kernel stack addresses. (CVE-2014-8133, Low)

* An information leak flaw was found in the Linux kernel's IEEE 802.11 wireless networking implementation. When software encryption was used, a remote attacker could use this flaw to leak up to 8 bytes of plaintext. (CVE-2014-8709, Low)

* It was found that the Linux kernel KVM subsystem's sysenter instruction emulation was not sufficient. An unprivileged guest user could use this flaw to escalate their privileges by tricking the hypervisor to emulate a SYSENTER instruction in 16-bit mode, if the guest OS did not initialize the SYSENTER model-specific registers (MSRs). Note: Certified guest operating systems for Scientific Linux with KVM do initialize the SYSENTER MSRs and are thus not vulnerable to this issue when running on a KVM hypervisor. (CVE-2015-0239, Low)
