Synopsis

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

Description

The SUSE Linux Enterprise 12 SP4 kernel was updated to receive various security and bugfixes.

The following security bugs were fixed :

CVE-2018-20855: An issue was discovered in the Linux kernel 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-2019-1125: Exclude ATOMs from speculation through SWAPGS (bsc#1139358).

CVE-2019-14283: In the Linux kernel, 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 could be triggered by an unprivileged local user when a floppy disk was inserted. NOTE: QEMU creates the floppy device by default.
(bnc#1143191)

CVE-2019-11810: An issue was discovered in the Linux kernel A NULL pointer dereference could occur when megasas_create_frame_pool() failed in megasas_alloc_cmds() in drivers/scsi/megaraid/megaraid_sas_base.c. This caused a Denial of Service, related to a use-after-free (bnc#1134399).

CVE-2019-13648: In the Linux kernel on the powerpc platform, when hardware transactional memory was disabled, a local user could cause a denial of service (TM Bad Thing exception and system crash) via a sigreturn() system call that sent a crafted signal frame.
(bnc#1142254)

CVE-2019-13631: In parse_hid_report_descriptor in drivers/input/tablet/gtco.c in the Linux kernel, a malicious USB device could send an HID report that triggered an out-of-bounds write during generation of debugging messages. (bnc#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.
