This script is Copyright (C) 2015 Tenable Network Security, Inc.

Synopsis :

The remote SUSE host is missing one or more security updates.

Description :

The SUSE Linux Enterprise 11 Service Pack 2 kernel was updated to
3.0.101 and also includes various other bug and security fixes.

A new feature was added :

- supported.conf: marked net/netfilter/xt_set as supported

The following security bugs have been fixed :

CVE-2013-4587: Array index error in the kvm_vm_ioctl_create_vcpu
function in virt/kvm/kvm_main.c in the KVM subsystem in the Linux
kernel through 3.12.5 allows local users to gain privileges via a
large id value. (bnc#853050)

CVE-2013-6368: The KVM subsystem in the Linux kernel through
3.12.5 allows local users to gain privileges or cause a
denial of service (system crash) via a VAPIC synchronization
operation involving a page-end address. (bnc#853052)

CVE-2013-6367: The apic_get_tmcct function in
arch/x86/kvm/lapic.c in the KVM subsystem in the Linux
kernel through 3.12.5 allows guest OS users to cause a
denial of service (divide-by-zero error and host OS crash)
via crafted modifications of the TMICT value. (bnc#853051)

CVE-2013-4592: Memory leak in the __kvm_set_memory_region
function in virt/kvm/kvm_main.c in the Linux kernel before
3.9 allows local users to cause a denial of service (memory
consumption) by leveraging certain device access to trigger
movement of memory slots. (bnc#851101)

CVE-2013-6378: The lbs_debugfs_write function in
drivers/net/wireless/libertas/debugfs.c in the Linux kernel
through 3.12.1 allows local users to cause a denial of
service (OOPS) by leveraging root privileges for a
zero-length write operation. (bnc#852559)

CVE-2013-4514: 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-2013-4515: 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-2013-7027: 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.

CVE-2013-4483: 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-2013-4511: 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-2013-6380: 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-2013-6463: 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 & msg_namelen message header
parameters. (bnc#854722)

CVE-2013-6383: 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-2013-4345: 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. (bnc#840226)
