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.

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

The following security bugs were fixed :

CVE-2019-15291: There was a NULL pointer dereference caused by a malicious USB device in the flexcop_usb_probe function in the drivers/media/usb/b2c2/flexcop-usb.c driver (bnc#1146540).

CVE-2019-14821: An out-of-bounds access issue was found in the way Linux kernel's KVM hypervisor implements the coalesced MMIO write operation. It operates on an MMIO ring buffer 'struct kvm_coalesced_mmio' object, wherein write indices 'ring->first' and 'ring->last' value could be supplied by a host user-space process. An unprivileged host user or process with access to '/dev/kvm' device could use this flaw to crash the host kernel, resulting in a denial of service or potentially escalating privileges on the system (bnc#1151350).

CVE-2017-18595: A double free may be caused by the function allocate_trace_buffer in the file kernel/trace/trace.c (bnc#1149555).

CVE-2019-9506: The Bluetooth BR/EDR specification up to and including version 5.1 permitted sufficiently low encryption key length and did not prevent an attacker from influencing the key length negotiation.
This allowed practical brute-force attacks (aka 'KNOB') that could decrypt traffic and injected arbitrary ciphertext without the victim noticing (bnc#1137865 bnc#1146042).

CVE-2019-14835: A buffer overflow flaw was found in the way Linux kernel's vhost functionality that translates virtqueue buffers to IOVs, logged the buffer descriptors during migration. A privileged guest user able to pass descriptors with invalid length to the host when migration is underway, could have used this flaw to increase their privileges on the host (bnc#1150112).

CVE-2019-15216: There was a NULL pointer dereference caused by a malicious USB device in the drivers/usb/misc/yurex.c driver (bnc#1146361).

CVE-2019-15924: fm10k_init_module in drivers/net/ethernet/intel/fm10k/fm10k_main.c had a NULL pointer dereference because there was no -ENOMEM upon an alloc_workqueue failure (bnc#1149612).

CVE-2019-9456: In the Pixel C USB monitor driver there was a possible OOB write due to a missing bounds check. This could have led to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation (bnc#1150025).

CVE-2019-15031: In the Linux kernel on the powerpc platform, a local user could have read vector registers of other users' processes via an interrupt. To exploit the vulnerability, a local user starts a transaction (via the hardware transactional memory instruction tbegin) and then accesses vector registers. At some point, the vector registers will be corrupted with the values from a different local Linux process, because MSR_TM_ACTIVE was misused in arch/powerpc/kernel/process.c (bnc#1149713).

CVE-2019-15030: In the Linux kernel on the powerpc platform, a local user could have read vector registers of other users' processes via a Facility Unavailable exception. To exploit the venerability, a local user starts a transaction (via the hardware transactional memory instruction tbegin) and then accesses vector registers. At some point, the vector registers will be corrupted with the values from a different local Linux process because of a missing arch/powerpc/kernel/process.c check (bnc#1149713).

CVE-2019-15920: SMB2_read in fs/cifs/smb2pdu.c had a use-after-free.
(bnc#1149626).

CVE-2019-15921: There was a memory leak issue when idr_alloc() fails in genl_register_family() in net/netlink/genetlink.c (bnc#1149602).

CVE-2018-21008: A use-after-free could have been caused by the function rsi_mac80211_detach in the file drivers/net/wireless/rsi/rsi_91x_mac80211.c (bnc#1149591).

CVE-2019-15919: SMB2_write in fs/cifs/smb2pdu.c had a use-after-free (bnc#1149552).

CVE-2019-15926: An out-of-bounds access existed in the functions ath6kl_wmi_pstream_timeout_event_rx and ath6kl_wmi_cac_event_rx in the file drivers/net/wireless/ath/ath6kl/wmi.c (bnc#1149527).

CVE-2019-15927: An out-of-bounds access existed in the function build_audio_procunit in the file sound/usb/mixer.c (bnc#1149522).

CVE-2019-15902: Misuse of the upstream 'x86/ptrace: Fix possible spectre-v1 in ptrace_get_debugreg()' commit reintroduced the Spectre vulnerability that it aimed to eliminate. This occurred because the backport process depends on cherry picking specific commits, and because two (correctly ordered) code lines were swapped (bnc#1149376).

CVE-2019-15666: There was an out-of-bounds array access in
__xfrm_policy_unlink, which will cause denial of service, because verify_newpolicy_info in net/xfrm/xfrm_user.c mishandled directory validation (bnc#1148394).

CVE-2019-15219: There was a NULL pointer dereference caused by a malicious USB device in the drivers/usb/misc/sisusbvga/sisusb.c driver (bnc#1146524).

CVE-2019-14814: There was a heap-based buffer overflow in the Marvell wifi chip driver, that allowed local users to cause a denial of service (system crash) or possibly execute arbitrary code (bnc#1146512).

The version of AOS installed on the remote host is prior to 5.19.0.5. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-5.19.0.5 advisory.

  - In Network Security Services (NSS) before 3.46, several cryptographic primitives had missing length     checks. In cases where the application calling the library did not perform a sanity check on the inputs it     could result in a crash due to a buffer overflow. (CVE-2019-17006)

  - Heap buffer overflow in the TFTP protocol handler in cURL 7.19.4 to 7.65.3. (CVE-2019-5482)

  - In all versions of cpio before 2.13 does not properly validate input files when generating TAR archives.
    When cpio is used to create TAR archives from paths an attacker can write to, the resulting archive may     contain files with permissions the attacker did not have or in paths he did not have access to. Extracting     those archives from a high-privilege user without carefully reviewing them may lead to the compromise of     the system. (CVE-2019-14866)

  - If an HTTP/2 client connecting to Apache Tomcat 10.0.0-M1 to 10.0.0-M7, 9.0.0.M1 to 9.0.37 or 8.5.0 to     8.5.57 exceeded the agreed maximum number of concurrent streams for a connection (in violation of the     HTTP/2 protocol), it was possible that a subsequent request made on that connection could contain HTTP     headers - including HTTP/2 pseudo headers - from a previous request rather than the intended headers. This     could lead to users seeing responses for unexpected resources. (CVE-2020-13943)

  - Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: Optimizer). Supported     versions that are affected are 5.6.45 and prior, 5.7.27 and prior and 8.0.17 and prior. Easily exploitable     vulnerability allows low privileged attacker with network access via multiple protocols to compromise     MySQL Server. Successful attacks of this vulnerability can result in unauthorized ability to cause a hang     or frequently repeatable crash (complete DOS) of MySQL Server. (CVE-2019-2974)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
