Updated kernel packages that fix multiple security issues and several bugs are now available for Red Hat Enterprise Linux 6.5 Extended Update Support.

Red Hat Product Security 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 race condition flaw was found in the way the Linux kernel's KVM subsystem handled PIT (Programmable Interval Timer) emulation. A guest user who has access to the PIT I/O ports could use this flaw to crash the host. (CVE-2014-3611, Important)

* A flaw was found in the way the Linux kernel's SCTP implementation validated INIT chunks when performing Address Configuration Change (ASCONF). A remote attacker could use this flaw to crash the system by sending a specially crafted SCTP packet to trigger a NULL pointer dereference on the system. (CVE-2014-7841, Important)

* A flaw was found in the way the ipc_rcu_putref() function in the Linux kernel's IPC implementation handled reference counter decrementing. A local, unprivileged user could use this flaw to trigger an Out of Memory (OOM) condition and, potentially, crash the system. (CVE-2013-4483, Moderate)

* A memory corruption flaw was found in the way the USB ConnectTech WhiteHEAT serial driver processed completion commands sent via USB Request Blocks buffers. An attacker with physical access to the system could use this flaw to crash the system or, potentially, escalate their privileges on the system. (CVE-2014-3185, Moderate)

* It was found that the Linux kernel's KVM subsystem did not handle the VM exits gracefully for the invept (Invalidate Translations Derived from EPT) and invvpid (Invalidate Translations Based on VPID) instructions. On hosts with an Intel processor and invept/invppid VM exit support, an unprivileged guest user could use these instructions to crash the guest. (CVE-2014-3645, CVE-2014-3646, Moderate)

* A flaw was found in the way the Linux kernel's netfilter subsystem handled generic protocol tracking. As demonstrated in the Stream Control Transmission Protocol (SCTP) case, a remote attacker could use this flaw to bypass intended iptables rule restrictions when the associated connection tracking module was not loaded on the system.
(CVE-2014-8160, Moderate)

Red Hat would like to thank Lars Bull of Google for reporting CVE-2014-3611, Vladimir Davydov (Parallels) for reporting CVE-2013-4483, and the Advanced Threat Research team at Intel Security for reporting CVE-2014-3645 and CVE-2014-3646. The CVE-2014-7841 issue was discovered by Liu Wei of Red Hat.

Bug fixes :

* When forwarding a packet, the iptables target TCPOPTSTRIP used the tcp_hdr() function to locate the option space. Consequently, TCPOPTSTRIP located the incorrect place in the packet, and therefore did not match options for stripping. TCPOPTSTRIP now uses the TCP header itself to locate the option space, and the options are now properly stripped. (BZ#1172026)

* The ipset utility computed incorrect values of timeouts from an old IP set, and these values were then supplied to a new IP set. A resize on an IP set with a timeouts option enabled could then supply corrupted data from an old IP set. This bug has been fixed by properly reading timeout values from an old set before supplying them to a new set. (BZ#1172763)

* Incorrect processing of errors from the BCM5719 LAN controller could result in incoming packets being dropped. Now, received errors are handled properly, and incoming packets are no longer randomly dropped.
(BZ#1180405)

* When the NVMe driver allocated a name-space queue, it was recognized as a request-based driver, whereas it was a BIO-based driver. While trying to access data during the loading of NVMe along with a request-based DM device, the system could terminate unexpectedly or become unresponsive. Now, NVMe does not set the QUEUE_FLAG_STACKABLE flag during the allocation of a name-space queue, and the system no longer attempts to insert a request into the queue, preventing a crash. (BZ#1180554)

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.

Updated kernel packages that fix multiple security issues, address several hundred bugs, and add numerous enhancements are now available as part of the ongoing support and maintenance of Red Hat Enterprise Linux version 6. This is the sixth regular update.

Red Hat Product Security 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 NULL pointer dereference flaw was found in the way the Linux kernel's Stream Control Transmission Protocol (SCTP) implementation handled simultaneous connections between the same hosts. A remote attacker could use this flaw to crash the system. (CVE-2014-5077, Important)

* An integer overflow flaw was found in the way the Linux kernel's Frame Buffer device implementation mapped kernel memory to user space via the mmap syscall. A local user able to access a frame buffer device file (/dev/fb*) could possibly use this flaw to escalate their privileges on the system. (CVE-2013-2596, Important)

* A flaw was found in the way the ipc_rcu_putref() function in the Linux kernel's IPC implementation handled reference counter decrementing. A local, unprivileged user could use this flaw to trigger an Out of Memory (OOM) condition and, potentially, crash the system. (CVE-2013-4483, Moderate)

* It was found that the permission checks performed by the Linux kernel when a netlink message was received were not sufficient. A local, unprivileged user could potentially bypass these restrictions by passing a netlink socket as stdout or stderr to a more privileged process and altering the output of this process. (CVE-2014-0181, Moderate)

* It was found that the try_to_unmap_cluster() function in the Linux kernel's Memory Managment subsystem did not properly handle page locking in certain cases, which could potentially trigger the BUG_ON() macro in the mlock_vma_page() function. A local, unprivileged user could use this flaw to crash the system. (CVE-2014-3122, Moderate)

* A flaw was found in the way the Linux kernel's kvm_iommu_map_pages() function handled IOMMU mapping failures. A privileged user in a guest with an assigned host device could use this flaw to crash the host.
(CVE-2014-3601, Moderate)

* Multiple use-after-free flaws were found in the way the Linux kernel's Advanced Linux Sound Architecture (ALSA) implementation handled user controls. A local, privileged user could use either of these flaws to crash the system. (CVE-2014-4653, CVE-2014-4654, CVE-2014-4655, Moderate)

* A flaw was found in the way the Linux kernel's VFS subsystem handled reference counting when performing unmount operations on symbolic links. A local, unprivileged user could use this flaw to exhaust all available memory on the system or, potentially, trigger a use-after-free error, resulting in a system crash or privilege escalation. (CVE-2014-5045, Moderate)

* An integer overflow flaw was found in the way the lzo1x_decompress_safe() function of the Linux kernel's LZO implementation processed Literal Runs. A local attacker could, in extremely rare cases, use this flaw to crash the system or, potentially, escalate their privileges on the system. (CVE-2014-4608, Low)

The remote Oracle Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2014-1392 advisory.

  - The ipc_rcu_putref function in ipc/util.c in the Linux kernel before 3.10 does not properly manage a     reference count, which allows local users to cause a denial of service (memory consumption or system     crash) via a crafted application. (CVE-2013-4483)

  - The Netlink implementation in the Linux kernel through 3.14.1 does not provide a mechanism for authorizing     socket operations based on the opener of a socket, which allows local users to bypass intended access     restrictions and modify network configurations by using a Netlink socket for the (1) stdout or (2) stderr     of a setuid program. (CVE-2014-0181)

  - 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.
    (CVE-2014-4653)

  - 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. (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 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. (CVE-2014-4655)

  - 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. (CVE-2014-5077)

  - The kvm_iommu_map_pages function in virt/kvm/iommu.c in the Linux kernel through 3.16.1 miscalculates the     number of pages during the handling of a mapping failure, which allows guest OS users to (1) cause a     denial of service (host OS memory corruption) or possibly have unspecified other impact by triggering a     large gfn value or (2) cause a denial of service (host OS memory consumption) by triggering a small gfn     value that leads to permanently pinned pages. (CVE-2014-3601)

  - The try_to_unmap_cluster function in mm/rmap.c in the Linux kernel before 3.14.3 does not properly     consider which pages must be locked, which allows local users to cause a denial of service (system crash)     by triggering a memory-usage pattern that requires removal of page-table mappings. (CVE-2014-3122)

  - Integer overflow in the fb_mmap function in drivers/video/fbmem.c in the Linux kernel before 3.8.9, as     used in a certain Motorola build of Android 4.1.2 and other products, allows local users to create a read-     write memory mapping for the entirety of kernel memory, and consequently gain privileges, via crafted     /dev/graphics/fb0 mmap2 system calls, as demonstrated by the Motochopper pwn program. (CVE-2013-2596)

  - ** DISPUTED ** Multiple integer overflows in the lzo1x_decompress_safe function in     lib/lzo/lzo1x_decompress_safe.c in the LZO decompressor in the Linux kernel before 3.15.2 allow context-     dependent attackers to cause a denial of service (memory corruption) via a crafted Literal Run. NOTE: the     author of the LZO algorithms says the Linux kernel is *not* affected; media hype. (CVE-2014-4608)

  - The mountpoint_last function in fs/namei.c in the Linux kernel before 3.15.8 does not properly maintain a     certain reference count during attempts to use the umount system call in conjunction with a symlink, which     allows local users to cause a denial of service (memory consumption or use-after-free) or possibly have     unspecified other impact via the umount program. (CVE-2014-5045)

  - Multiple buffer overflows in     drivers/staging/wlags49_h2/wl_priv.c in the Linux kernel     before 3.12 allow local users to cause a denial of     service or possibly have unspecified other impact by     leveraging the CAP_NET_ADMIN capability and providing a     long station-name string, related to the (1)     wvlan_uil_put_info and (2) wvlan_set_station_nickname     functions. (bnc#849029). (CVE-2013-4514)

  - The bcm_char_ioctl function in     drivers/staging/bcm/Bcmchar.c in the Linux kernel before     3.12 does not initialize a certain data structure, which     allows local users to obtain sensitive information from     kernel memory via an IOCTL_BCM_GET_DEVICE_DRIVER_INFO     ioctl call. (bnc#849034). (CVE-2013-4515)

  - The ieee80211_radiotap_iterator_init function in     net/wireless/radiotap.c in the Linux kernel before     3.11.7 does not check whether a frame contains any data     outside of the header, which might allow attackers to     cause a denial of service (buffer over-read) via a     crafted header. (bnc#854634). (CVE-2013-7027)

  - The ipc_rcu_putref function in ipc/util.c in the Linux     kernel before 3.10 does not properly manage a reference     count, which allows local users to cause a denial of     service (memory consumption or system crash) via a     crafted application. (bnc#848321). (CVE-2013-4483)

  - Multiple integer overflows in Alchemy LCD frame-buffer     drivers in the Linux kernel before 3.12 allow local     users to create a read-write memory mapping for the     entirety of kernel memory, and consequently gain     privileges, via crafted mmap operations, related to the     (1) au1100fb_fb_mmap function in     drivers/video/au1100fb.c and the (2) au1200fb_fb_mmap     function in drivers/video/au1200fb.c. (bnc#849021).
    (CVE-2013-4511)

  - The aac_send_raw_srb function in     drivers/scsi/aacraid/commctrl.c in the Linux kernel     through 3.12.1 does not properly validate a certain size     value, which allows local users to cause a denial of     service (invalid pointer dereference) or possibly have     unspecified other impact via an FSACTL_SEND_RAW_SRB     ioctl call that triggers a crafted SRB command.
    (bnc#852373). (CVE-2013-6380)

  - Linux kernel built with the networking     support(CONFIG_NET) is vulnerable to an information     leakage flaw in the socket layer. It could occur while     doing recvmsg(2), recvfrom(2) socket calls. It occurs     due to improperly initialised msg_name &amp; msg_namelen     message header parameters. (bnc#854722). (CVE-2013-6463)

  - The aac_compat_ioctl function in     drivers/scsi/aacraid/linit.c in the Linux kernel before     3.11.8 does not require the CAP_SYS_RAWIO capability,     which allows local users to bypass intended access     restrictions via a crafted ioctl call. (bnc#852558).
    (CVE-2013-6383)

  - Off-by-one error in the get_prng_bytes function in     crypto/ansi_cprng.c in the Linux kernel through 3.11.4     makes it easier for context-dependent attackers to     defeat cryptographic protection mechanisms via multiple     requests for small amounts of data, leading to improper     management of the state of the consumed data.

Multiple vulnerabilities has been found and corrected in the Linux kernel :

The ipc_rcu_putref function in ipc/util.c in the Linux kernel before 3.10 does not properly manage a reference count, which allows local users to cause a denial of service (memory consumption or system crash) via a crafted application (CVE-2013-4483).

The skb_flow_dissect function in net/core/flow_dissector.c in the Linux kernel through 3.12 allows remote attackers to cause a denial of service (infinite loop) via a small value in the IHL field of a packet with IPIP encapsulation (CVE-2013-4348).

The Linux kernel before 3.12, when UDP Fragmentation Offload (UFO) is enabled, does not properly initialize certain data structures, which allows local users to cause a denial of service (memory corruption and system crash) or possibly gain privileges via a crafted application that uses the UDP_CORK option in a setsockopt system call and sends both short and long packets, related to the ip_ufo_append_data function in net/ipv4/ip_output.c and the ip6_ufo_append_data function in net/ipv6/ip6_output.c (CVE-2013-4470).

The ext4_orphan_del function in fs/ext4/namei.c in the Linux kernel before 3.7.3 does not properly handle orphan-list entries for non-journal filesystems, which allows physically proximate attackers to cause a denial of service (system hang) via a crafted filesystem on removable media, as demonstrated by the e2fsprogs tests/f_orphan_extents_inode/image.gz test (CVE-2013-2015).

net/ipv6/ip6_output.c in the Linux kernel through 3.11.4 does not properly determine the need for UDP Fragmentation Offload (UFO) processing of small packets after the UFO queueing of a large packet, which allows remote attackers to cause a denial of service (memory corruption and system crash) or possibly have unspecified other impact via network traffic that triggers a large response packet (CVE-2013-4387).

The IPv6 SCTP implementation in net/sctp/ipv6.c in the Linux kernel through 3.11.1 uses data structures and function calls that do not trigger an intended configuration of IPsec encryption, which allows remote attackers to obtain sensitive information by sniffing the network (CVE-2013-4350).

The updated packages provides a solution for these security issues.
