Upstream stable release 3.9.9 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 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)

  - Multiple array index errors in drivers/hid/hid-core.c     in the Human Interface Device (HID) subsystem in the     Linux kernel through 3.11 allow physically proximate     attackers to execute arbitrary code or cause a denial     of service (heap memory corruption) via a crafted     device that provides an invalid Report     ID.(CVE-2013-2888)

  - drivers/hid/hid-zpff.c in the Human Interface Device     (HID) subsystem in the Linux kernel through 3.11, when     CONFIG_HID_ZEROPLUS is enabled, allows physically     proximate attackers to cause a denial of service     (heap-based out-of-bounds write) via a crafted     device.(CVE-2013-2889)

  - drivers/hid/hid-pl.c in the Human Interface Device     (HID) subsystem in the Linux kernel through 3.11, when     CONFIG_HID_PANTHERLORD is enabled, allows physically     proximate attackers to cause a denial of service     (heap-based out-of-bounds write) via a crafted     device.(CVE-2013-2892)

  - A flaw was found in the way the get_dumpable() function     return value was interpreted in the ptrace subsystem of     the Linux kernel. When 'fs.suid_dumpable' was set to 2,     a local, unprivileged local user could use this flaw to     bypass intended ptrace restrictions and obtain     potentially sensitive information.(CVE-2013-2929)

  - 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-2013-2930)

  - The fib6_add_rt2node function in net/ipv6/ip6_fib.c in     the IPv6 stack in the Linux kernel through 3.10.1 does     not properly handle Router Advertisement (RA) messages     in certain circumstances involving three routes that     initially qualified for membership in an ECMP route set     until a change occurred for one of the first two     routes, which allows remote attackers to cause a denial     of service (system crash) via a crafted sequence of     messages.(CVE-2013-4125)

  - Use-after-free vulnerability in the     vhost_net_set_backend function in drivers/vhost/net.c     in the Linux kernel through 3.10.3 allows local users     to cause a denial of service (OOPS and system crash)     via vectors involving powering on a virtual     machine.(CVE-2013-4127)

  - The udp_v6_push_pending_frames function in     net/ipv6/udp.c in the IPv6 implementation in the Linux     kernel through 3.10.3 makes an incorrect function call     for pending data, 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-2013-4162)

  - 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)

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

The remote Oracle Linux 5 / 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2013-2543 advisory.
