The version of AOS installed on the remote host is prior to 5.11.2.1. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-5.11.2.1 advisory.

  - In Sudo before 1.8.28, an attacker with access to a Runas ALL sudoer account can bypass certain policy     blacklists and session PAM modules, and can cause incorrect logging, by invoking sudo with a crafted user     ID. For example, this allows bypass of !root configuration, and USER= logging, for a sudo -u     \#$((0xffffffff)) command. (CVE-2019-14287)

  - A denial of service vulnerability was found in rsyslog in the imptcp module. An attacker could send a     specially crafted message to the imptcp socket, which would cause rsyslog to crash. Versions before 8.27.0     are vulnerable. (CVE-2018-16881)

  - Vulnerability in the Java SE, Java SE Embedded product of Oracle Java SE (component: Networking).
    Supported versions that are affected are Java SE: 7u231, 8u221, 11.0.4 and 13; Java SE Embedded: 8u221.
    Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple     protocols to compromise Java SE, Java SE Embedded. Successful attacks require human interaction from a     person other than the attacker. Successful attacks of this vulnerability can result in unauthorized     ability to cause a partial denial of service (partial DOS) of Java SE, Java SE Embedded. Note: This     vulnerability applies to Java deployments, typically in clients running sandboxed Java Web Start     applications or sandboxed Java applets (in Java SE 8), that load and run untrusted code (e.g., code that     comes from the internet) and rely on the Java sandbox for security. This vulnerability does not apply to     Java deployments, typically in servers, that load and run only trusted code (e.g., code installed by an     administrator). (CVE-2019-2945)

  - Vulnerability in the Java SE, Java SE Embedded product of Oracle Java SE (component: Kerberos). Supported     versions that are affected are Java SE: 7u231, 8u221, 11.0.4 and 13; Java SE Embedded: 8u221. Difficult to     exploit vulnerability allows unauthenticated attacker with network access via Kerberos to compromise Java     SE, Java SE Embedded. While the vulnerability is in Java SE, Java SE Embedded, attacks may significantly     impact additional products. Successful attacks of this vulnerability can result in unauthorized access to     critical data or complete access to all Java SE, Java SE Embedded accessible data. Note: This     vulnerability applies to Java deployments, typically in clients running sandboxed Java Web Start     applications or sandboxed Java applets (in Java SE 8), that load and run untrusted code (e.g., code that     comes from the internet) and rely on the Java sandbox for security. This vulnerability can also be     exploited by using APIs in the specified Component, e.g., through a web service which supplies data to the     APIs. (CVE-2019-2949)

The version of AOS installed on the remote host is prior to 5.11.3. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-5.11.3 advisory.

  - OpenSLP as used in ESXi and the Horizon DaaS appliances has a heap overwrite issue. VMware has evaluated     the severity of this issue to be in the Critical severity range with a maximum CVSSv3 base score of 9.8.
    (CVE-2019-5544)

  - A heap overflow flaw was found in the Linux kernel, all versions 3.x.x and 4.x.x before 4.18.0, in Marvell     WiFi chip driver. The vulnerability allows a remote attacker to cause a system crash, resulting in a     denial of service, or execute arbitrary code. The highest threat with this vulnerability is with the     availability of the system. If code execution occurs, the code will run with the permissions of root. This     will affect both confidentiality and integrity of files on the system. (CVE-2019-14901)

  - In Sudo before 1.8.28, an attacker with access to a Runas ALL sudoer account can bypass certain policy     blacklists and session PAM modules, and can cause incorrect logging, by invoking sudo with a crafted user     ID. For example, this allows bypass of !root configuration, and USER= logging, for a sudo -u     \#$((0xffffffff)) command. (CVE-2019-14287)

  - Empty or malformed p256-ECDH public keys may trigger a segmentation fault due values being improperly     sanitized before being copied into memory and used. This vulnerability affects Firefox ESR < 60.8, Firefox     < 68, and Thunderbird < 60.8. (CVE-2019-11729)

  - When encrypting with a block cipher, if a call to NSC_EncryptUpdate was made with data smaller than the     block size, a small out of bounds write could occur. This could have caused heap corruption and a     potentially exploitable crash. This vulnerability affects Thunderbird < 68.3, Firefox ESR < 68.3, and     Firefox < 71. (CVE-2019-11745)

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

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

The following security bugs were fixed :

CVE-2019-12819: The function __mdiobus_register() called put_device(), which triggered a fixed_mdio_bus_init use-after-free. This would cause a denial of service. (bsc#1138291)

CVE-2019-12818: The nfc_llcp_build_tlv function in net/nfc/llcp_commands.c may return NULL. If the caller does not check for this, it will trigger a NULL pointer dereference. This will cause denial of service. This used to affect nfc_llcp_build_gb in net/nfc/llcp_core.c. (bsc#1138293)

CVE-2019-11477: A sequence of SACKs may have been crafted such that one can trigger an integer overflow, leading to a kernel panic.

CVE-2019-11478: It was possible to send a crafted sequence of SACKs which will fragment the TCP retransmission queue. An attacker may have been able to further exploit the fragmented queue to cause an expensive linked-list walk for subsequent SACKs received for that same TCP connection.

CVE-2019-11479: An attacker could force the Linux kernel to segment its responses into multiple TCP segments. This would drastically increased the bandwidth required to deliver the same amount of data.
Further, it would consume additional resources such as CPU and NIC processing power.

CVE-2019-3846: A flaw that allowed an attacker to corrupt memory and possibly escalate privileges was found in the mwifiex kernel module while connecting to a malicious wireless network. (bsc#1136424)

CVE-2019-10124: An issue was discovered in the hwpoison implementation in mm/memory-failure.c in the Linux kernel. When soft_offline_in_use_page() runs on a thp tail page after pmd is split, an attacker could cause a denial of service (bsc#1130699, CVE-2019-10124).

CVE-2019-12382: An issue was discovered in drm_load_edid_firmware in drivers/gpu/drm/drm_edid_load.c in the Linux kernel There was an unchecked kstrdup of fwstr, which might allow an attacker to cause a denial of service (NULL pointer dereference and system crash).
(bsc#1136586)

CVE-2019-11487: The Linux kernel allowed page reference count overflow, with resultant use-after-free issues, if about 140 GiB of RAM exists. This is related to fs/fuse/dev.c, fs/pipe.c, fs/splice.c, include/linux/mm.h, include/linux/pipe_fs_i.h, kernel/trace/trace.c, mm/gup.c, and mm/hugetlb.c. It could occur with FUSE requests.
(bbsc#1133190)

CVE-2019-5489: The mincore() implementation in mm/mincore.c in the Linux kernel allowed local attackers to observe page cache access patterns of other processes on the same system, potentially allowing sniffing of secret information. (Fixing this affects the output of the fincore program.) Limited remote exploitation may be possible, as demonstrated by latency differences in accessing public files from an Apache HTTP Server. (bsc#1120843)

CVE-2019-11833: fs/ext4/extents.c in the Linux kernel did not zero out the unused memory region in the extent tree block, which might allow local users to obtain sensitive information by reading uninitialized data in the filesystem. (bsc#1135281)

CVE-2019-11091: Microarchitectural Data Sampling Uncacheable Memory (MDSUM): Uncacheable memory on some microprocessors utilizing speculative execution may have allowed an authenticated user to potentially enable information disclosure via a side channel with local access. A list of impacted products can be found here :

CVE-2019-11815: An issue was discovered in rds_tcp_kill_sock in net/rds/tcp.c in the Linux kernel There was a race condition leading to a use-after-free, related to net namespace cleanup. (bsc#1135278)

CVE-2019-11884: The do_hidp_sock_ioctl function in net/bluetooth/hidp/sock.c in the Linux kernel allowed a local user to obtain potentially sensitive information from kernel stack memory via a hidPCONNADD command, because a name field may not end with a '\0' character. (bsc#1134848)

CVE-2019-11811: An issue was discovered in the Linux kernel There was a use-after-free upon attempted read access to /proc/ioports after the ipmi_si module was removed, related to drivers/char/ipmi/ipmi_si_intf.c, drivers/char/ipmi/ipmi_si_mem_io.c, and drivers/char/ipmi/ipmi_si_port_io.c. (bsc#1134397)

CVE-2019-11486: The Siemens R3964 line discipline driver in drivers/tty/n_r3964.c in the Linux kernel has multiple race conditions. (bsc#1133188)

CVE-2019-9003: In the Linux kernel, attackers could trigger a drivers/char/ipmi/ipmi_msghandler.c use-after-free and OOPS by arranging for certain simultaneous execution of the code, as demonstrated by a 'service ipmievd restart' loop. (bsc#1126704)

CVE-2018-16880: A flaw was found in the Linux kernel's handle_rx() function in the [vhost_net] driver. A malicious virtual guest, under specific conditions, could trigger an out-of-bounds write in a kmalloc-8 slab on a virtual host which may have lead to a kernel memory corruption and a system panic. Due to the nature of the flaw, privilege escalation cannot be fully ruled out.(bsc#1122767)

CVE-2019-9503: An issue was discoved which meant that brcmfmac frame validation could be bypassed. (bsc#1132828)

CVE-2019-9500: An issue was discovered that lead to brcmfmac heap buffer overflow. (bsc#1132681)

CVE-2019-8564: An issue was discoved which meant that brcmfmac frame validation could be bypassed. (bsc#1132673)

CVE-2017-5753: Systems with microprocessors utilizing speculative execution and branch prediction may have allowed unauthorized disclosure of information to an attacker with local user access via a side-channel analysis.

CVE-2019-3882: A flaw was found in the Linux kernel's vfio interface implementation that permitted violation of the user's locked memory limit. If a device was bound to a vfio driver, such as vfio-pci, and the local attacker is administratively granted ownership of the device, it may have caused a system memory exhaustion and thus a denial of service (DoS). (bsc#1131427)
