The remote SUSE host is missing one or more security updates.
The SUSE Linux Enterprise 11 SP3 LTSS 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 existed in the encrypted-keys handling. (bnc#1094353). - CVE-2018-1000204: A malformed SG_IO ioctl issued for a SCSI device could lead to a local kernel information 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: A NULL pointer dereference in dccp_write_xmit() function in net/dccp/output.c 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 can 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 kernel could result in local attackers being able to crash the kernel or potentially elevate privileges because kmalloc_array is not used (bnc#1098016 1100418). - CVE-2018-3620: Local attackers on baremetal systems could use speculative code patterns on hyperthreaded processors to read data present in the L1 Datacache used by other hyperthreads on the same CPU core, potentially leaking sensitive data. (bnc#1087081). - CVE-2018-3646: Local attackers in virtualized guest systems could use speculative code patterns on hyperthreaded processors to read data present in the L1 Datacache used by other hyperthreads on the same CPU core, potentially leaking sensitive data, even from other virtual machines or the host system. (bnc#1089343). - 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 could 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 allowing 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). The update package also includes non-security fixes. See advisory for details. Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
