Updated kernel packages that fix three security issues and several bugs are now available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having Important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

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

* A flaw was found in the way the Linux kernel's netfilter connection tracking implementation for Datagram Congestion Control Protocol (DCCP) packets used the skb_header_pointer() function. A remote attacker could use this flaw to send a specially crafted DCCP packet to crash the system or, potentially, escalate their privileges on the system. (CVE-2014-2523, Important)

* A flaw was found in the way the Linux kernel's Adaptec RAID controller (aacraid) checked permissions of compat IOCTLs. A local attacker could use this flaw to bypass intended security restrictions.
(CVE-2013-6383, Moderate)

* A flaw was found in the way the handle_rx() function handled large network packets when mergeable buffers were disabled. A privileged guest user could use this flaw to crash the host or corrupt QEMU process memory on the host, which could potentially result in arbitrary code execution on the host with the privileges of the QEMU process. (CVE-2014-0077, Moderate)

The CVE-2014-0077 issue was discovered by Michael S. Tsirkin of Red Hat.

This update also fixes several bugs. Documentation for these changes will be available shortly from the Technical Notes document linked to in the References section.

All kernel users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect.

(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)

Updated kernel packages that fix two security issues and one bug are now available for Red Hat Enterprise Linux 6.3 Extended Update Support.

The Red Hat Security Response Team has rated this update as having Important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

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

* A flaw was found in the way the Linux kernel's netfilter connection tracking implementation for Datagram Congestion Control Protocol (DCCP) packets used the skb_header_pointer() function. A remote attacker could use this flaw to send a specially crafted DCCP packet to crash the system or, potentially, escalate their privileges on the system. (CVE-2014-2523, Important)

* A flaw was found in the way the handle_rx() function handled large network packets when mergeable buffers were disabled. A privileged guest user could use this flaw to crash the host or corrupt QEMU process memory on the host, which could potentially result in arbitrary code execution on the host with the privileges of the QEMU process. (CVE-2014-0077, Moderate)

The CVE-2014-0077 issue was discovered by Michael S. Tsirkin of Red Hat.

This update also fixes the following bug :

* Prior to this update, a guest-provided value was used as the head length of the socket buffer allocated on the host. If the host was under heavy memory load and the guest-provided value was too large, the allocation could have failed, resulting in stalls and packet drops in the guest's Tx path. With this update, the guest-provided value has been limited to a reasonable size so that socket buffer allocations on the host succeed regardless of the memory load on the host, and guests can send packets without experiencing packet drops or stalls.
(BZ#1092350)

All kernel users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect.

The 3.13.8 stable update contains a number of important fixes across the tree.

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

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 :

  - The atalk_recvmsg function in net/appletalk/ddp.c in     the Linux kernel before 3.12.4 updates a certain length     value without ensuring that an associated data     structure has been initialized, which allows local     users to obtain sensitive information from kernel     memory via a (1) recvfrom, (2) recvmmsg, or (3) recvmsg     system call.(CVE-2013-7267i1/4%0

  - fs/f2fs/segment.c in the Linux kernel allows local     users to cause a denial of service (NULL pointer     dereference and panic) by using a noflush_merge option     that triggers a NULL value for a flush_cmd_control data     structure.(CVE-2017-18241i1/4%0

  - fs/pnode.c in the Linux kernel before 4.5.4 does not     properly traverse a mount propagation tree in a certain     case involving a slave mount, which allows local users     to cause a denial of service (NULL pointer dereference     and OOPS) via a crafted series of mount system     calls.(CVE-2016-4581i1/4%0

  - 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.(CVE-2014-0077i1/4%0

  - It was found that the fix for CVE-2016-9576 was     incomplete: the Linux kernel's sg implementation did     not properly restrict write operations in situations     where the KERNEL_DS option is set. A local attacker to     read or write to arbitrary kernel memory locations or     cause a denial of service (use-after-free) by     leveraging write access to a /dev/sg     device.(CVE-2016-10088i1/4%0

  - ** DISPUTED ** An issue was discovered in the Linux     kernel through 4.17.2. Since the page allocator does     not yield CPU resources to the owner of the oom_lock     mutex, a local unprivileged user can trivially lock up     the system forever by wasting CPU resources from the     page allocator (e.g., via concurrent page fault events)     when the global OOM killer is invoked. NOTE: the     software maintainer has not accepted certain proposed     patches, in part because of a viewpoint that 'the     underlying problem is non-trivial to     handle.'(CVE-2016-10723i1/4%0

  - A flaw was found in the way the Linux kernel's ASN.1     DER decoder processed certain certificate files with     tags of indefinite length. A local, unprivileged user     could use a specially crafted X.509 certificate DER     file to crash the system or, potentially, escalate     their privileges on the system.(CVE-2016-0758i1/4%0

  - A flaw was found in the way the Linux kernel's Stream     Control Transmission Protocol (SCTP) implementation     handled the association's output queue. A remote     attacker could send specially crafted packets that     would cause the system to use an excessive amount of     memory, leading to a denial of     service.(CVE-2014-3688i1/4%0

  - A use-after-free flaw was found in the way the     ping_init_sock() function of the Linux kernel handled     the group_info reference counter. A local, unprivileged     user could use this flaw to crash the system or,     potentially, escalate their privileges on the     system.(CVE-2014-2851i1/4%0

  - The compat_get_timex function in kernel/compat.c in the     Linux kernel before 4.16.9 allows local users to obtain     sensitive information from kernel memory via     adjtimex.(CVE-2018-11508i1/4%0

  - The cdc_parse_cdc_header() function in     'drivers/usb/core/message.c' in the Linux kernel,     before 4.13.6, allows local users to cause a denial of     service (out-of-bounds read and system crash) or     possibly have unspecified other impact via a crafted     USB device. Due to the nature of the flaw, privilege     escalation cannot be fully ruled out, although we     believe it is unlikely.(CVE-2017-16534i1/4%0

  - A flaw was found in the crypto subsystem of the Linux     kernel before version kernel-4.15-rc4. The 'null     skcipher' was being dropped when each af_alg_ctx was     freed instead of when the aead_tfm was freed. This can     cause the null skcipher to be freed while it is still     in use leading to a local user being able to crash the     system or possibly escalate     privileges.(CVE-2018-14619i1/4%0

  - The crypto_skcipher_init_tfm function in     crypto/skcipher.c in the Linux kernel through 4.11.2     relies on a setkey function that lacks a key-size     check, which allows local users to cause a denial of     service (NULL pointer dereference) via a crafted     application.(CVE-2017-9211i1/4%0

  - kernel/events/core.c in the performance subsystem in     the Linux kernel before 4.0 mismanages locks during     certain migrations, which allows local users to gain     privileges via a crafted application, aka Android     internal bug 30955111.(CVE-2016-6786i1/4%0

  - The KEYS subsystem in the Linux kernel omitted an     access-control check when writing a key to the current     task's default keyring, allowing a local user to bypass     security checks to the keyring. This compromises the     validity of the keyring for those who rely on     it.(CVE-2017-17807i1/4%0

  - A use-after-free flaw was found in the way the Linux     kernel's SCTP implementation handled authentication key     reference counting during INIT collisions. A remote     attacker could use this flaw to crash the system or,     potentially, escalate their privileges on the     system.(CVE-2015-1421i1/4%0

  - The waitid implementation in kernel/exit.c in the Linux     kernel through 4.13.4 accesses rusage data structures     in unintended cases. This can allow local users to     obtain sensitive information and bypass the KASLR     protection mechanism via a crafted system     call.(CVE-2017-14954i1/4%0

  - It was found that the Linux kernel's keyring     implementation would leak memory when adding a key to a     keyring via the add_key() function. A local attacker     could use this flaw to exhaust all available memory on     the system.(CVE-2015-1333i1/4%0

  - The msm_ipc_router_close function in     net/ipc_router/ipc_router_socket.c in the ipc_router     component for the Linux kernel 3.x, as used in Qualcomm     Innovation Center (QuIC) Android contributions for MSM     devices and other products, allow attackers to cause a     denial of service (NULL pointer dereference) or     possibly have unspecified other impact by triggering     failure of an accept system call for an AF_MSM_IPC     socket.(CVE-2016-5870i1/4%0

  - A reachable assertion failure flaw was found in the     Linux kernel built with KVM virtualisation(CONFIG_KVM)     support with Virtual Function I/O feature (CONFIG_VFIO)     enabled. This failure could occur if a malicious guest     device sent a virtual interrupt (guest IRQ) with a     larger (i1/4z1024) index value.(CVE-2017-1000252i1/4%0
