The Linux kernel was updated to fix bugs and security issues :

Following security issues were fixed: CVE-2015-2830: A flaw was found in the way the Linux kernels 32-bit emulation implementation handled forking or closing of a task with an int80 entry. A local user could have potentially used this flaw to escalate their privileges on the system.

CVE-2015-2042: A kernel information leak in rds sysctl files was fixed.

CVE-2014-9683: Off-by-one error in the ecryptfs_decode_from_filename function in fs/ecryptfs/crypto.c in the eCryptfs subsystem in the Linux kernel allowed local users to cause a denial of service (buffer overflow and system crash) or possibly gain privileges via a crafted filename.

CVE-2015-0275: A BUG_ON in ext4 was fixed which could be triggered by local users.

CVE-2015-2666: A buffer overflow when loading microcode files into the kernel could be used by the administrator to execute code in the kernel, bypassing secure boot measures.

  - CVE-2015-1421: Use-after-free vulnerability in the     sctp_assoc_update function in net/sctp/associola.c in     the Linux kernel allowed remote attackers to cause a     denial of service (slab corruption and panic) or     possibly have unspecified other impact by triggering an     INIT collision that leads to improper handling of     shared-key data.

  - CVE-2015-2150: XSA-120: Guests were permitted to modify     all bits of the PCI command register of passed through     cards, which could lead to Host system crashes.

  - CVE-2015-0777: The XEN usb backend could leak     information to the guest system due to copying     uninitialized memory.

  - CVE-2015-1593: A integer overflow reduced the     effectiveness of the stack randomization on 64-bit     systems.

  - CVE-2014-9419: The __switch_to function in     arch/x86/kernel/process_64.c in the Linux kernel did not     ensure that Thread Local Storage (TLS) descriptors are     loaded before proceeding with other steps, which made it     easier for local users to bypass the ASLR protection     mechanism via a crafted application that reads a TLS     base address.

  - CVE-2014-9428: The batadv_frag_merge_packets function in     net/batman-adv/fragmentation.c in the B.A.T.M.A.N.
    implementation in the Linux kernel used an incorrect     length field during a calculation of an amount of     memory, which allowed remote attackers to cause a denial     of service (mesh-node system crash) via fragmented     packets.

  - CVE-2014-8160:
    net/netfilter/nf_conntrack_proto_generic.c in the Linux     kernel generated incorrect conntrack entries during     handling of certain iptables rule sets for the SCTP,     DCCP, GRE, and UDP-Lite protocols, which allowed remote     attackers to bypass intended access restrictions via     packets with disallowed port numbers.

  - CVE-2014-9529: Race condition in the key_gc_unused_keys     function in security/keys/gc.c in the Linux kernel     allowed local users to cause a denial of service (memory     corruption or panic) or possibly have unspecified other     impact via keyctl commands that trigger access to a key     structure member during garbage collection of a key.

  - CVE-2014-9420: The rock_continue function in     fs/isofs/rock.c in the Linux kernel did not restrict the     number of Rock Ridge continuation entries, which allowed     local users to cause a denial of service (infinite loop,     and system crash or hang) via a crafted iso9660 image.

  - CVE-2014-9584: The parse_rock_ridge_inode_internal     function in fs/isofs/rock.c in the Linux kernel did not     validate a length value in the Extensions Reference (ER)     System Use Field, which allowed local users to obtain     sensitive information from kernel memory via a crafted     iso9660 image.

  - CVE-2014-9585: The vdso_addr function in     arch/x86/vdso/vma.c in the Linux kernel did not properly     choose memory locations for the vDSO area, which made it     easier for local users to bypass the ASLR protection     mechanism by guessing a location at the end of a PMD.

  - CVE-2014-8559: The d_walk function in fs/dcache.c in the     Linux kernel through did not properly maintain the     semantics of rename_lock, which allowed local users to     cause a denial of service (deadlock and system hang) via     a crafted application.

  - CVE-2014-8134: The paravirt_ops_setup function in     arch/x86/kernel/kvm.c in the Linux kernel used an     improper paravirt_enabled setting for KVM guest kernels,     which made it easier for guest OS users to bypass the     ASLR protection mechanism via a crafted application that     reads a 16-bit value.

The SUSE Linux Enterprise 11 Service Pack 1 LTSS kernel was updated to fix security issues on kernels on the x86_64 architecture.

The following security bugs have been fixed :

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

  - CVE-2014-8160: SCTP firewalling failed until the SCTP     module was loaded (bnc#913059).

  - CVE-2014-9584: The parse_rock_ridge_inode_internal     function in fs/isofs/rock.c in the Linux kernel before     3.18.2 did not validate a length value in the Extensions     Reference (ER) System Use Field, which allowed local     users to obtain sensitive information from kernel memory     via a crafted iso9660 image (bnc#912654).

  - CVE-2014-9585: The vdso_addr function in     arch/x86/vdso/vma.c in the Linux kernel through 3.18.2     did not properly choose memory locations for the vDSO     area, which made it easier for local users to bypass the     ASLR protection mechanism by guessing a location at the     end of a PMD (bnc#912705).

  - CVE-2014-9420: The rock_continue function in     fs/isofs/rock.c in the Linux kernel through 3.18.1 did     not restrict the number of Rock Ridge continuation     entries, which allowed local users to cause a denial of     service (infinite loop, and system crash or hang) via a     crafted iso9660 image (bnc#911325).

  - CVE-2014-0181: The Netlink implementation in the Linux     kernel through 3.14.1 did not provide a mechanism for     authorizing socket operations based on the opener of a     socket, which allowed 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 (bnc#875051).

  - CVE-2010-5313: Race condition in arch/x86/kvm/x86.c in     the Linux kernel before 2.6.38 allowed L2 guest OS users     to cause a denial of service (L1 guest OS crash) via a     crafted instruction that triggers an L2 emulation     failure report, a similar issue to CVE-2014-7842     (bnc#907822).

  - CVE-2014-7842: Race condition in arch/x86/kvm/x86.c in     the Linux kernel before 3.17.4 allowed guest OS users to     cause a denial of service (guest OS crash) via a crafted     application that performs an MMIO transaction or a PIO     transaction to trigger a guest userspace emulation error     report, a similar issue to CVE-2010-5313 (bnc#905312).

  - CVE-2014-3688: The SCTP implementation in the Linux     kernel before 3.17.4 allowed remote attackers to cause a     denial of service (memory consumption) by triggering a     large number of chunks in an associations output queue,     as demonstrated by ASCONF probes, related to     net/sctp/inqueue.c and net/sctp/sm_statefuns.c     (bnc#902351).

  - CVE-2014-3687: The sctp_assoc_lookup_asconf_ack function     in net/sctp/associola.c in the SCTP implementation in     the Linux kernel through 3.17.2 allowed remote attackers     to cause a denial of service (panic) via duplicate     ASCONF chunks that trigger an incorrect uncork within     the side-effect interpreter (bnc#902349).

  - CVE-2014-3673: The SCTP implementation in the Linux     kernel through 3.17.2 allowed remote attackers to cause     a denial of service (system crash) via a malformed     ASCONF chunk, related to net/sctp/sm_make_chunk.c and     net/sctp/sm_statefuns.c (bnc#902346).

  - CVE-2014-7841: The sctp_process_param function in     net/sctp/sm_make_chunk.c in the SCTP implementation in     the Linux kernel before 3.17.4, when ASCONF is used,     allowed remote attackers to cause a denial of service     (NULL pointer dereference and system crash) via a     malformed INIT chunk (bnc#905100).

  - CVE-2014-8709: The ieee80211_fragment function in     net/mac80211/tx.c in the Linux kernel before 3.13.5 did     not properly maintain a certain tail pointer, which     allowed remote attackers to obtain sensitive cleartext     information by reading packets (bnc#904700).

  - CVE-2013-7263: The Linux kernel before 3.12.4 updated     certain length values before ensuring that associated     data structures have been initialized, which allowed     local users to obtain sensitive information from kernel     stack memory via a (1) recvfrom, (2) recvmmsg, or (3)     recvmsg system call, related to net/ipv4/ping.c,     net/ipv4/raw.c, net/ipv4/udp.c, net/ipv6/raw.c, and     net/ipv6/udp.c (bnc#857643).

  - CVE-2012-6657: The sock_setsockopt function in     net/core/sock.c in the Linux kernel before 3.5.7 did not     ensure that a keepalive action is associated with a     stream socket, which allowed local users to cause a     denial of service (system crash) by leveraging the     ability to create a raw socket (bnc#896779).

  - CVE-2014-3185: Multiple buffer overflows in the     command_port_read_callback function in     drivers/usb/serial/whiteheat.c in the Whiteheat USB     Serial Driver in the Linux kernel before 3.16.2 allowed     physically proximate attackers to execute arbitrary code     or cause a denial of service (memory corruption and     system crash) via a crafted device that provides a large     amount of (1) EHCI or (2) XHCI data associated with a     bulk response (bnc#896391).

  - CVE-2014-3184: The report_fixup functions in the HID     subsystem in the Linux kernel before 3.16.2 might allow     physically proximate attackers to cause a denial of     service (out-of-bounds write) via a crafted device that     provides a small report descriptor, related to (1)     drivers/hid/hid-cherry.c, (2) drivers/hid/hid-kye.c, (3)     drivers/hid/hid-lg.c, (4) drivers/hid/hid-monterey.c,     (5) drivers/hid/hid-petalynx.c, and (6)     drivers/hid/hid-sunplus.c (bnc#896390).

The update package also includes non-security fixes. See advisory for details.

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.

Updated kernel packages that fix multiple security issues and several bugs are now available for Red Hat Enterprise Linux 7.

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.

* It was found that the Linux kernel's implementation of vectored pipe read and write functionality did not take into account the I/O vectors that were already processed when retrying after a failed atomic access operation, potentially resulting in memory corruption due to an I/O vector array overrun. A local, unprivileged user could use this flaw to crash the system or, potentially, escalate their privileges on the system. (CVE-2015-1805, Important)

* A race condition flaw was found in the way the Linux kernel keys management subsystem performed key garbage collection. A local attacker could attempt accessing a key while it was being garbage collected, which would cause the system to crash. (CVE-2014-9529, Moderate)

* A flaw was found in the way the Linux kernel's 32-bit emulation implementation handled forking or closing of a task with an 'int80' entry. A local user could potentially use this flaw to escalate their privileges on the system. (CVE-2015-2830, Low)

* It was found that the Linux kernel's ISO file system implementation did not correctly limit the traversal of Rock Ridge extension Continuation Entries (CE). An attacker with physical access to the system could use this flaw to trigger an infinite loop in the kernel, resulting in a denial of service. (CVE-2014-9420, Low)

* An information leak flaw was found in the way the Linux kernel's ISO9660 file system implementation accessed data on an ISO9660 image with RockRidge Extension Reference (ER) records. An attacker with physical access to the system could use this flaw to disclose up to 255 bytes of kernel memory. (CVE-2014-9584, Low)

* A flaw was found in the way the nft_flush_table() function of the Linux kernel's netfilter tables implementation flushed rules that were referencing deleted chains. A local user who has the CAP_NET_ADMIN capability could use this flaw to crash the system. (CVE-2015-1573, Low)

* An integer overflow flaw was found in the way the Linux kernel randomized the stack for processes on certain 64-bit architecture systems, such as x86-64, causing the stack entropy to be reduced by four. (CVE-2015-1593, Low)

Red Hat would like to thank Carl Henrik Lunde for reporting CVE-2014-9420 and CVE-2014-9584. The security impact of the CVE-2015-1805 issue was discovered by Red Hat.
