Synopsis

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

Description

The SUSE Linux Enterprise 15 SP1 RT kernel was updated to receive various security and bugfixes.

The following security bugs were fixed :

CVE-2019-15916: Fixed a memory leak in register_queue_kobjects() which might have led denial of service (bsc#1149448).

CVE-2019-0154: Fixed an improper access control in subsystem for Intel (R) processor graphics whichs may have allowed an authenticated user to potentially enable denial of service via local access (bsc#1135966).

CVE-2019-0155: Fixed an improper access control in subsystem for Intel (R) processor graphics whichs may have allowed an authenticated user to potentially enable escalation of privilege via local access (bsc#1135967).

CVE-2019-16231: Fixed a NULL pointer dereference due to lack of checking the alloc_workqueue return value (bsc#1150466).

CVE-2019-18805: Fixed an integer overflow in tcp_ack_update_rtt() leading to a denial of service or possibly unspecified other impact (bsc#1156187).

CVE-2019-17055: Enforced CAP_NET_RAW in the AF_ISDN network module to restrict unprivileged users to create a raw socket (bsc#1152782).

CVE-2019-16995: Fixed a memory leak in hsr_dev_finalize() which may have caused denial of service (bsc#1152685).

CVE-2019-11135: Aborting an asynchronous TSX operation on Intel CPUs with Transactional Memory support could be used to facilitate sidechannel information leaks out of microarchitectural buffers, similar to the previously described 'Microarchitectural Data Sampling' attack.(bsc#1139073). The Linux kernel was supplemented with the option to disable TSX operation altogether (requiring CPU Microcode updates on older systems) and better flushing of microarchitectural buffers (VERW). The set of options available is described in our TID at https://www.suse.com/support/kb/doc/?id=7024251

CVE-2019-16233: drivers/scsi/qla2xxx/qla_os.c did not check the alloc_workqueue return value, leading to a NULL pointer dereference.
(bsc#1150457).

CVE-2018-12207: Untrusted virtual machines on Intel CPUs could exploit a race condition in the Instruction Fetch Unit of the Intel CPU to cause a Machine Exception during Page Size Change, causing the CPU core to be non-functional.

CVE-2019-10220: Added sanity checks on the pathnames passed to the user space. (bsc#1144903)

CVE-2019-17666: rtlwifi: Fix potential overflow in P2P code (bsc#1154372).

CVE-2019-16232: Fix a potential NULL pointer dereference in the Marwell libertas driver (bsc#1150465).

CVE-2019-16234: iwlwifi pcie driver did not check the alloc_workqueue return value, leading to a NULL pointer dereference. (bsc#1150452).

CVE-2019-17133: cfg80211 wireless extension did not reject a long SSID IE, leading to a Buffer Overflow (bsc#1153158).

CVE-2019-17056: The AF_NFC network module did not enforce CAP_NET_RAW, which meant that unprivileged users could create a raw socket (bsc#1152788).

CVE-2019-15291: Fixed a NULL pointer dereference caused by a malicious USB device in the flexcop_usb_probe function (bsc#1146519).

CVE-2019-14821: Fixed an out-of-bounds access resulting in a denial of service or potentially escalating privileges on the system (bnc#1151350).

CVE-2017-18595: Fixed a double free which caused by the function allocate_trace_buffer (bsc#1149555).

CVE-2019-9506: Fixed an issue with Bluetooth which permited low encryption key length and did not prevent an attacker from influencing the key length negotiation allowing brute-force attacks (bsc#1137865).

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.
