"According to the versions of the kernel packages installed, the
EulerOS installation on the remote host is affected by the following
vulnerabilities :

  - The kernel package contains the Linux kernel (vmlinuz),
    the core of any Linux operating system. The kernel
    handles the basic functions of the operating system:
    memory allocation, process allocation, device input and
    output, etc.Security
    Fix(es):drivers/media/usb/dvb-usb/technisat-usb2.c in
    the Linux kernel through 5.2.9 has an out-of-bounds
    read via crafted USB device traffic (which may be
    remote via usbip or usbredir).(CVE-2019-15505)An issue
    was discovered in the Linux kernel through 5.2.13.
    nbd_genl_status in drivers/blockbd.c does not check the
    nla_nest_start_noflag return
    value.(CVE-2019-16089)drivers/scsi/qla2xxx/qla_os.c in
    the Linux kernel 5.2.14 does not check the
    alloc_workqueue return value, leading to a NULL pointer
    dereference.(CVE-2019-16233)In the Linux kernel before
    5.2.14, rds6_inc_info_copy in net/rds/recv.c allows
    attackers to obtain sensitive information from kernel
    stack memory because tos and flags fields are not
    initialized.(CVE-2019-16714)drivers/
    net/wireless/rsi/rsi_91x_usb.c in the Linux kernel
    through 5.2.9 has a Double Free via crafted USB device
    traffic (which may be remote via usbip or
    usbredir).(CVE-2019-15504)There is heap-based buffer
    overflow in Linux kernel, all versions up to, excluding
    5.3, in the marvell wifi chip driver in Linux kernel,
    that allows local users to cause a denial of
    service(system crash) or possibly execute arbitrary
    code.(CVE-2019-14814)There is heap-based buffer
    overflow in marvell wifi chip driver in Linux
    kernel,allows local users to cause a denial of
    service(system crash) or possibly execute arbitrary
    code.(CVE-2019-14815)There is heap-based buffer
    overflow in kernel, all versions up to, excluding 5.3,
    in the marvell wifi chip driver in Linux kernel, that
    allows local users to cause a denial of service(system
    crash) or possibly execute arbitrary
    code.(CVE-2019-14816)drivers/
    net/wireless/ath/ath6kl/usb.c in the Linux kernel
    through 5.2.9 has a NULL pointer dereference via an
    incomplete address in an endpoint
    descriptor.(CVE-2019-15098)drivers/
    net/wireless/ath/ath10k/usb.c in the Linux kernel
    through 5.2.8 has a NULL pointer dereference via an
    incomplete address in an endpoint
    descriptor.(CVE-2019-15099)

description block directly from the EulerOS security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.");
