Synopsis
The remote SUSE host is missing one or more security updates.Description
The SUSE Linux Enterprise 12 SP1 kernel was updated to receive various security and bugfixes.The following security bugs were fixed :
CVE-2019-1125: Enable Spectre v1 swapgs mitigations (bsc#1139358).
CVE-2018-20855: An issue was discovered in create_qp_common in drivers/infiniband/hw/mlx5/qp.c, mlx5_ib_create_qp_resp was never initialized, resulting in a leak of stack memory to userspace (bsc#1143045).
CVE-2019-14284: The drivers/block/floppy.c allowed a denial of service by setup_format_params division-by-zero. Two consecutive ioctls can trigger the bug: the first one should set the drive geometry with .sect and .rate values that make F_SECT_PER_TRACK be zero. Next, the floppy format operation should be called. It can be triggered by an unprivileged local user even when a floppy disk has not been inserted.
NOTE: QEMU creates the floppy device by default (bsc#1143189).
CVE-2019-14283: The function set_geometry in drivers/block/floppy.c did not validate the sect and head fields, as demonstrated by an integer overflow and out-of-bounds read. It can be triggered by an unprivileged local user when a floppy disk has been inserted. NOTE:
QEMU creates the floppy device by default (bsc#1143191).
CVE-2019-11810: A NULL pointer dereference can occur when megasas_create_frame_pool() fails in megasas_alloc_cmds() in drivers/scsi/megaraid/megaraid_sas_base.c. This causes a Denial of Service, related to a use-after-free (bsc#1134399).
CVE-2019-13648: In the Linux kernel on the powerpc platform, when hardware transactional memory is disabled, a local user can cause a denial of service (TM Bad Thing exception and system crash) via a sigreturn() system call that sends a crafted signal frame. This affects arch/powerpc/kernel/signal_32.c and arch/powerpc/kernel/signal_64.c (bnc#1142254).
CVE-2019-13631: In parse_hid_report_descriptor in drivers/input/tablet/gtco.c, a malicious USB device can send an HID report that triggers an out-of-bounds write during generation of debugging messages (bsc#1142023).
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.
