The ip6_append_data_mtu function in net/ipv6/ip6_output.c in the IPv6 implementation in the Linux kernel through 3.10.3 does not properly maintain information about whether the IPV6_MTU setsockopt option had been specified, which allows local users to cause a denial of service (BUG and system crash) via a crafted application that uses the UDP_CORK option in a setsockopt system call.

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

  - net/ceph/auth_none.c in the Linux kernel through 3.10     allows remote attackers to cause a denial of service     (NULL pointer dereference and system crash) or possibly     have unspecified other impact via an auth_reply message     that triggers an attempted build_request     operation.(CVE-2013-1059)

  - The dispatch_discard_io function in     drivers/block/xen-blkback/blkback.c in the Xen blkback     implementation in the Linux kernel before 3.10.5 allows     guest OS users to cause a denial of service (data loss)     via filesystem write operations on a read-only disk     that supports the (1) BLKIF_OP_DISCARD (aka discard or     TRIM) or (2) SCSI UNMAP feature.(CVE-2013-2140)

  - The mmc_ioctl_cdrom_read_data function in     drivers/cdrom/cdrom.c in the Linux kernel through 3.10     allows local users to obtain sensitive information from     kernel memory via a read operation on a malfunctioning     CD-ROM drive.(CVE-2013-2164)

  - The ip6_append_data_mtu function in     net/ipv6/ip6_output.c in the IPv6 implementation in the     Linux kernel through 3.10.3 does not properly maintain     information about whether the IPV6_MTU setsockopt     option had been specified, which allows local users to     cause a denial of service (BUG and system crash) via a     crafted application that uses the UDP_CORK option in a     setsockopt system call.(CVE-2013-4163)

  - Memory leak in the unshare_userns function in     kernel/user_namespace.c in the Linux kernel before     3.10.6 allows local users to cause a denial of service     (memory consumption) via an invalid CLONE_NEWUSER     unshare call.(CVE-2013-4205)

  - Off-by-one error in the build_unc_path_to_root function     in fs/cifs/connect.c in the Linux kernel before 3.9.6     allows remote attackers to cause a denial of service     (memory corruption and system crash) via a DFS share     mount operation that triggers use of an unexpected DFS     referral name length.(CVE-2013-4247)

  - The net_ctl_permissions function in net/sysctl_net.c in     the Linux kernel before 3.11.5 does not properly     determine uid and gid values, which allows local users     to bypass intended /proc/sys/net restrictions via a     crafted application.(CVE-2013-4270)

  - 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.(CVE-2013-4299)

  - The scm_check_creds function in net/core/scm.c in the     Linux kernel before 3.11 performs a capability check in     an incorrect namespace, which allows local users to     gain privileges via PID spoofing.(CVE-2013-4300)

  - It was found that the Linux kernel did not properly     account file descriptors passed over the unix socket     against the process limit. A local user could use this     flaw to exhaust all available memory on the     system.(CVE-2013-4312)

  - Use-after-free vulnerability in drivers/net/tun.c in     the Linux kernel through 3.11.1 allows local users to     gain privileges by leveraging the CAP_NET_ADMIN     capability and providing an invalid tuntap interface     name in a TUNSETIFF ioctl call.(CVE-2013-4343)

  - 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.(CVE-2013-4345)

The remote OracleVM system is missing necessary patches to address critical security updates : please see Oracle VM Security Advisory OVMSA-2017-0057 for details.

Updated kernel-rt packages that fix several security issues and multiple bugs are now available for Red Hat Enterprise MRG 2.3.

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

This update fixes the following security issues :

* A heap-based buffer overflow flaw was found in the Linux kernel's iSCSI target subsystem. A remote attacker could use a specially crafted iSCSI request to cause a denial of service on a system or, potentially, escalate their privileges on that system. (CVE-2013-2850, Important)

* A flaw was found in the Linux kernel's Performance Events implementation. On systems with certain Intel processors, a local, unprivileged user could use this flaw to cause a denial of service by leveraging the perf subsystem to write into the reserved bits of the OFFCORE_RSP_0 and OFFCORE_RSP_1 model-specific registers.
(CVE-2013-2146, Moderate)

* An invalid pointer dereference flaw was found in the Linux kernel's TCP/IP protocol suite implementation. A local, unprivileged user could use this flaw to crash the system or, potentially, escalate their privileges on the system by using sendmsg() with an IPv6 socket connected to an IPv4 destination. (CVE-2013-2232, Moderate)

* Two flaws were found in the way the Linux kernel's TCP/IP protocol suite implementation handled IPv6 sockets that used the UDP_CORK option. A local, unprivileged user could use these flaws to cause a denial of service. (CVE-2013-4162, CVE-2013-4163, Moderate)

* A flaw was found in the Linux kernel's Chipidea USB driver. A local, unprivileged user could use this flaw to cause a denial of service.
(CVE-2013-2058, Low)

* Information leak flaws in the Linux kernel could allow a privileged, local user to leak kernel memory to user-space. (CVE-2013-2147, CVE-2013-2164, CVE-2013-2234, CVE-2013-2237, Low)

* Information leak flaws in the Linux kernel could allow a local, unprivileged user to leak kernel memory to user-space. (CVE-2013-2141, CVE-2013-2148, Low)

* A format string flaw was found in the Linux kernel's block layer. A privileged, local user could potentially use this flaw to escalate their privileges to kernel level (ring0). (CVE-2013-2851, Low)

* A format string flaw was found in the b43_do_request_fw() function in the Linux kernel's b43 driver implementation. A local user who is able to specify the 'fwpostfix' b43 module parameter could use this flaw to cause a denial of service or, potentially, escalate their privileges. (CVE-2013-2852, Low)

* A NULL pointer dereference flaw was found in the Linux kernel's ftrace and function tracer implementations. A local user who has the CAP_SYS_ADMIN capability could use this flaw to cause a denial of service. (CVE-2013-3301, Low)

Red Hat would like to thank Kees Cook for reporting CVE-2013-2850, CVE-2013-2851, and CVE-2013-2852; and Hannes Frederic Sowa for reporting CVE-2013-4162 and CVE-2013-4163.

This update also fixes the following bugs :

* The following drivers have been updated, fixing a number of bugs:
myri10ge, bna, enic, mlx4, bgmac, bcma, cxgb3, cxgb4, qlcnic, r8169, be2net, e100, e1000, e1000e, igb, ixgbe, brcm80211, cpsw, pch_gbe, bfin_mac, bnx2x, bnx2, cnic, tg3, and sfc. (BZ#974138)

* The realtime kernel was not built with the CONFIG_NET_DROP_WATCH kernel configuration option enabled. As such, attempting to run the dropwatch command resulted in the following error :

Unable to find NET_DM family, dropwatch can't work Cleaning up on socket creation error

With this update, the realtime kernel is built with the CONFIG_NET_DROP_WATCH option, allowing dropwatch to work as expected.
(BZ#979417)

The remote Oracle Linux 5 / 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2013-2546 advisory.

  - The mmc_ioctl_cdrom_read_data function in drivers/cdrom/cdrom.c in the Linux kernel through 3.10 allows     local users to obtain sensitive information from kernel memory via a read operation on a malfunctioning     CD-ROM drive. (CVE-2013-2164)

  - The (1) key_notify_sa_flush and (2) key_notify_policy_flush functions in net/key/af_key.c in the Linux     kernel before 3.10 do not initialize certain structure members, which allows local users to obtain     sensitive information from kernel heap memory by reading a broadcast message from the notify interface of     an IPSec key_socket. (CVE-2013-2234)

  - The isofs_export_encode_fh function in fs/isofs/export.c in the Linux kernel before 3.6 does not     initialize a certain structure member, which allows local users to obtain sensitive information from     kernel heap memory via a crafted application. (CVE-2012-6549)

  - The log_prefix function in kernel/printk.c in the Linux kernel 3.x before 3.4.33 does not properly remove     a prefix string from a syslog header, which allows local users to cause a denial of service (buffer     overflow and system crash) by leveraging /dev/kmsg write access and triggering a call_console_drivers     function call. (CVE-2013-1772)

  - The dispatch_discard_io function in drivers/block/xen-blkback/blkback.c in the Xen blkback implementation     in the Linux kernel before 3.10.5 allows guest OS users to cause a denial of service (data loss) via     filesystem write operations on a read-only disk that supports the (1) BLKIF_OP_DISCARD (aka discard or     TRIM) or (2) SCSI UNMAP feature. (CVE-2013-2140)

  - The crypto API in the Linux kernel through 3.9-rc8 does not initialize certain length variables, which     allows local users to obtain sensitive information from kernel stack memory via a crafted recvmsg or     recvfrom system call, related to the hash_recvmsg function in crypto/algif_hash.c and the skcipher_recvmsg     function in crypto/algif_skcipher.c. (CVE-2013-3076)

  - The ip6_append_data_mtu function in net/ipv6/ip6_output.c in the IPv6 implementation in the Linux kernel     through 3.10.3 does not properly maintain information about whether the IPV6_MTU setsockopt option had     been specified, which allows local users to cause a denial of service (BUG and system crash) via a crafted     application that uses the UDP_CORK option in a setsockopt system call. (CVE-2013-4163)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
