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).
