SuSE 11.2 Security Update : Linux kernel (SAT Patch Numbers 8779 / 8791 / 8792)

This script is Copyright (C) 2014 Tenable Network Security, Inc.

Synopsis :

The remote SuSE 11 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
(bnc#851066)(fate#313309) The following security bugs
have been fixed :

- 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).

- 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).

- 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).

- 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).

- 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).

- 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
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).

- 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 & 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).

- 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). (CVE-2013-4345)
