______________________________________________________________________________
An update that solves 13 vulnerabilities and has 18 fixes
is now available.
Description:
The SUSE Linux Enterprise 11 SP4 RT kernel was updated to receive various
security and bugfixes.
The following security bugs were fixed:
- CVE-2016-8405: An information disclosure vulnerability in kernel
components including the ION subsystem, Binder, USB driver and
networking subsystem could enable a local malicious application to
access data outside of its permission levels. (bnc#1099942).
- CVE-2017-13305: A information disclosure vulnerability was fixed in the
encrypted-keys handling. (bnc#1094353).
- CVE-2018-1000204: A malformed SG_IO ioctl issued for a SCSI device lead
to a local kernel data leak manifesting in up to approximately 1000
memory pages copied to the userspace. The problem has limited scope as
non-privileged users usually have no permissions to access SCSI device
files. (bnc#1096728).
- CVE-2018-1068: A flaw was found in the implementation of 32-bit syscall
interface for bridging. This allowed a privileged user to arbitrarily
write to a limited range of kernel memory (bnc#1085107).
- CVE-2018-1130: Linux kernel was vulnerable to a null pointer dereference
in dccp_write_xmit() function in net/dccp/output.c in that allowed a
local user to cause a denial of service by a number of certain crafted
system calls (bnc#1092904).
- CVE-2018-12233: In the ea_get function in fs/jfs/xattr.c a memory
corruption bug in JFS could be triggered by calling setxattr twice with
two different extended attribute names on the same file. This
vulnerability can be triggered by an unprivileged user with the ability
to create files and execute programs. A kmalloc call is incorrect,
leading to slab-out-of-bounds in jfs_xattr (bnc#1097234).
- CVE-2018-13053: The alarm_timer_nsleep function in
kernel/time/alarmtimer.c had an integer overflow via a large relative
timeout because ktime_add_safe is not used (bnc#1099924).
- CVE-2018-13406: An integer overflow in the uvesafb_setcmap function in
drivers/video/fbdev/uvesafb.c could result in local attackers being able
to crash the kernel or potentially elevate privileges because
kmalloc_array is not used (bnc#1098016 bnc#1100418).
- CVE-2018-3620: Systems with microprocessors utilizing speculative
execution and address translations may allow unauthorized disclosure of
information residing in the L1 data cache to an attacker with local user
access via a terminal page fault and a side-channel analysis
(bnc#1087081).
- CVE-2018-3646: Systems with microprocessors utilizing speculative
execution and address translations may allow unauthorized disclosure of
information residing in the L1 data cache to an attacker with local user
access with guest OS privilege via a terminal page fault and a
side-channel analysis (bnc#1089343 bnc#1104365).
- CVE-2018-5803: An error in the "_sctp_make_chunk()" function
(net/sctp/sm_make_chunk.c) when handling SCTP packets length could be
exploited to cause a kernel crash (bnc#1083900).
- CVE-2018-5814: Multiple race condition errors when handling probe,
disconnect, and rebind operations can be exploited to trigger a
use-after-free condition or a NULL pointer dereference by sending
multiple USB over IP packets (bnc#1096480).
- CVE-2018-7492: A NULL pointer dereference was found in the
net/rds/rdma.c __rds_rdma_map() function allowed local attackers to
cause a system panic and a denial-of-service, related to RDS_GET_MR and
RDS_GET_MR_FOR_DEST (bnc#1082962).
