New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote SUSE host is missing one or more security updates.

Description

The SUSE Linux Enterprise 12 SP2 kernel was updated to receive various security and bugfixes.

The following security bugs were fixed :

CVE-2019-3819: A flaw was fixed in the function hid_debug_events_read() in drivers/hid/hid-debug.c file which may have enter an infinite loop with certain parameters passed from a userspace. A local privileged user ('root') could have caused a system lock up and a denial of service (bnc#1123161).

CVE-2019-15118: Fixed kernel stack exhaustion in check_input_term in sound/usb/mixer.c via mishandled recursion (bnc#1145922).

CVE-2019-15117: Fixed out-of-bounds memory access in parse_audio_mixer_unit in sound/usb/mixer.c via mishandled short descriptor (bnc#1145920).

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-2019-13631: 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).

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-2019-1125: Enable Spectre v1 swapgs mitigations (bsc#1139358).

CVE-2019-10207: Check for missing tty operations in bluetooth/hci_uart (bsc#1142857).

CVE-2018-20856: Fixed a use-after-free issue in block/blk-core.c, where certain error case are mishandled (bnc#1143048).

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-2017-18551: An issue was discovered in drivers/i2c/i2c-core-smbus.c in the Linux kernel There was an out of bounds write in the function i2c_smbus_xfer_emulated (bnc#1146163).

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.
