script_set_attribute(attribute:"description", value:
"According to the versions of the kernel packages installed, the
EulerOS Virtualization for ARM 64 installation on the remote host is
affected by the following vulnerabilities :
- Linux kernel built with the KVM visualization support
(CONFIG_KVM), with nested visualization(nVMX) feature
enabled(nested=1), is vulnerable to host memory leakage
issue. It could occur while emulating VMXON instruction
in 'handle_vmon'. An L1 guest user could use this flaw
to leak host memory potentially resulting in
DoS.(CVE-2017-2596i1/4%0
- The (1) BPF_S_ANC_NLATTR and (2) BPF_S_ANC_NLATTR_NEST
extension implementations in the sk_run_filter function
in net/core/filter.c in the Linux kernel through 3.14.3
do not check whether a certain length value is
sufficiently large, which allows local users to cause a
denial of service (integer underflow and system crash)
via crafted BPF instructions. NOTE: the affected code
was moved to the __skb_get_nlattr and
__skb_get_nlattr_nest functions before the
vulnerability was announced.(CVE-2014-3144i1/4%0
- A flaw was found in the Linux kernel when freeing pages
in hugetlbfs. This could trigger a local denial of
service by crashing the kernel.(CVE-2017-15127i1/4%0
- An issue was discovered in the Linux kernel before 4.8.
Incorrect access checking in overlayfs mounts could be
used by local attackers to modify or truncate files in
the underlying filesystem.(CVE-2018-16597i1/4%0
- Memory leak in the cuse_channel_release function in
fs/fuse/cuse.c in the Linux kernel before 4.4 allows
local users to cause a denial of service (memory
consumption) or possibly have unspecified other impact
by opening /dev/cuse many times.(CVE-2015-1339i1/4%0
- A flaw was found in the way the Linux kernel's nested
NMI handler and espfix64 functionalities interacted
during NMI processing. A local, unprivileged user could
use this flaw to crash the system or, potentially,
escalate their privileges on the
system.(CVE-2015-3290i1/4%0
- Multiple array index errors in
drivers/hid/hid-multitouch.c in the Human Interface
Device (HID) subsystem in the Linux kernel through
3.11, when CONFIG_HID_MULTITOUCH is enabled, allow
physically proximate attackers to cause a denial of
service (heap memory corruption, or NULL pointer
dereference and OOPS) via a crafted
device.(CVE-2013-2897i1/4%0
- A flaw was found in the way the Linux kernel's futex
subsystem handled the requeuing of certain Priority
Inheritance (PI) futexes. A local, unprivileged user
could use this flaw to escalate their privileges on the
system.(CVE-2014-3153i1/4%0
- The XFS subsystem in the Linux kernel 4.4 and later
allows local users to cause a denial of service
(fdatasync() failure and system hang) by using the vfs
syscall group in the 'trinity' program, as a result of
a page lock order bug in the XFS seek hole/data
implementation.(CVE-2016-8660i1/4%0
- A flaw was found in the Linux kernel's key management
system where it was possible for an attacker to
escalate privileges or crash the machine. If a user key
gets negatively instantiated, an error code is cached
in the payload area. A negatively instantiated key may
be then be positively instantiated by updating it with
valid data. However, the -i1/4zupdate key type method
must be aware that the error code may be
there.(CVE-2015-8539i1/4%0
- It was found that the Linux kernel KVM subsystem's
sysenter instruction emulation was not sufficient. An
unprivileged guest user could use this flaw to escalate
their privileges by tricking the hypervisor to emulate
a SYSENTER instruction in 16-bit mode, if the guest OS
did not initialize the SYSENTER model-specific
registers (MSRs). Note: Certified guest operating
systems for Red Hat Enterprise Linux with KVM do
initialize the SYSENTER MSRs and are thus not
vulnerable to this issue when running on a KVM
hypervisor.(CVE-2015-0239i1/4%0
- An information leak flaw was found in the way the Linux
kernel handled media device enumerate entities IOCTL
requests. A local user able to access the /dev/media0
device file could use this flaw to leak kernel memory
bytes.(CVE-2014-1739i1/4%0
- The dgnc_mgmt_ioctl function in
drivers/staging/dgnc/dgnc_mgmt.c in the Linux kernel
through 4.3.3 does not initialize a certain structure
member, which allows local users to obtain sensitive
information from kernel memory via a crafted
application.(CVE-2015-7885i1/4%0
- An information leak was discovered in the Linux kernel
in cdrom_ioctl_drive_status() function in
drivers/cdrom/cdrom.c that could be used by local
attackers to read kernel memory at certain
location.(CVE-2018-16658i1/4%0
- A flaw was discovered in the Linux kernel's
implementation of VFIO. An attacker issuing an ioctl
can create a situation where memory is corrupted and
modify memory outside of the expected area. This may
overwrite kernel memory and subvert kernel
execution.(CVE-2016-9083i1/4%0
- It was found that the Linux kernel's KVM subsystem did
not handle the VM exits gracefully for the invvpid
(Invalidate Translations Based on VPID) instructions.
On hosts with an Intel processor and invppid VM exit
support, an unprivileged guest user could use these
instructions to crash the guest.(CVE-2014-3646i1/4%0
- An attacker on a network could abuse a flaw in the IPv6
stack fragment reassembly code to induce kernel memory
corruption on the system, possibly leading to a system
crash.(CVE-2016-9755i1/4%0
- It was found that a regular user could remove xattr
permissions on files by using the chown or write system
calls. A local attacker could use this flaw to deny
elevated permissions from valid users, services, or
applications, potentially resulting in a denial of
service.(CVE-2015-1350i1/4%0
- arch/powerpc/kvm/book3s_hv_rmhandlers.S in the Linux
kernel through 4.7 on PowerPC platforms, when
CONFIG_KVM_BOOK3S_64_HV is enabled, allows guest OS
users to cause a denial of service (host OS infinite
loop) by making a H_CEDE hypercall during the existence
of a suspended transaction.(CVE-2016-5412i1/4%0
- An issue was discovered in the proc_pid_stack function
in fs/proc/base.c in the Linux kernel. An attacker with
a local account can trick the stack unwinder code to
leak stack contents to userspace. The fix allows only
root to inspect the kernel stack of an arbitrary
task.(CVE-2018-17972i1/4%0

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.");
