updates.");
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 :
- Array index error in the tcm_vhost_make_tpg function in
drivers/vhost/scsi.c in the Linux kernel before 4.0
might allow guest OS users to cause a denial of service
(memory corruption) or possibly have unspecified other
impact via a crafted VHOST_SCSI_SET_ENDPOINT ioctl
call. NOTE: the affected function was renamed to
vhost_scsi_make_tpg before the vulnerability was
announced.(CVE-2015-4036i1/4%0
- The llc_cmsg_rcv function in net/llc/af_llc.c in the
Linux kernel before 4.5.5 does not initialize a certain
data structure, which allows attackers to obtain
sensitive information from kernel stack memory by
reading a message.(CVE-2016-4485i1/4%0
- The nr_recvmsg function in net/netrom/af_netrom.c in
the Linux kernel before 3.12.4 updates a certain length
value without ensuring that an associated data
structure has been initialized, which allows local
users to obtain sensitive information from kernel
memory via a (1) recvfrom, (2) recvmmsg, or (3) recvmsg
system call.(CVE-2013-7269i1/4%0
- The mct_u232_msr_to_state function in
drivers/usb/serial/mct_u232.c in the Linux kernel
before 4.5.1 allows physically proximate attackers to
cause a denial of service (NULL pointer dereference and
system crash) via a crafted USB device without two
interrupt-in endpoint descriptors.(CVE-2016-3136i1/4%0
- An out-of-bounds memory access flaw, CVE-2014-7825, was
found in the syscall tracing functionality of the Linux
kernel's perf subsystem. A local, unprivileged user
could use this flaw to crash the system. Additionally,
an out-of-bounds memory access flaw, CVE-2014-7826, was
found in the syscall tracing functionality of the Linux
kernel's ftrace subsystem. On a system with ftrace
syscall tracing enabled, a local, unprivileged user
could use this flaw to crash the system, or escalate
their privileges.(CVE-2014-7826i1/4%0
- Linux kernel built with the Kernel-based Virtual
Machine (CONFIG_KVM) support is vulnerable to a null
pointer dereference flaw. It could occur on x86
platform, when emulating an undefined instruction. An
attacker could use this flaw to crash the host kernel
resulting in DoS.(CVE-2016-8630i1/4%0
- A flaw was found in the Linux kernel's ext4 filesystem.
A local user can cause an out-of-bound access in
ext4_get_group_info function, a denial of service, and
a system crash by mounting and operating on a crafted
ext4 filesystem image.(CVE-2018-10881i1/4%0
- The arch_timer_reg_read_stable macro in
arch/arm64/include/asm/arch_timer.h in the Linux kernel
before 4.13 allows local users to cause a denial of
service (infinite recursion) by writing to a file under
/sys/kernel/debug in certain circumstances, as
demonstrated by a scenario involving debugfs, ftrace,
PREEMPT_TRACER, and
FUNCTION_GRAPH_TRACER.(CVE-2017-18261i1/4%0
- The ip6_route_add function in net/ipv6/route.c in the
Linux kernel through 3.13.6 does not properly count the
addition of routes, which allows remote attackers to
cause a denial of service (memory consumption) via a
flood of ICMPv6 Router Advertisement
packets.(CVE-2014-2309i1/4%0
- In the Linux kernel before 4.20.2, kernel/sched/fair.c
mishandles leaf cfs_rq's, which allows attackers to
cause a denial of service (infinite loop in
update_blocked_averages) or possibly have unspecified
other impact by inducing a high load.(CVE-2018-20784i1/4%0
- An issue was discovered in the F2FS filesystem code in
fs/f2fs/inline.c in the Linux kernel. A denial of
service due to the out-of-bounds memory access can
occur for a modified f2fs filesystem
image.(CVE-2018-13099i1/4%0
- An out-of-bounds write vulnerability was found in the
Linux kernel's vmw_surface_define_ioctl() function, in
the 'drivers/gpu/drm/vmwgfx/vmwgfx_surface.c' file. Due
to the nature of the flaw, privilege escalation cannot
be fully ruled out, although we believe it is
unlikely.(CVE-2017-7294i1/4%0
- A flaw was found in the way the Linux kernel's KVM
subsystem handled non-canonical addresses when
emulating instructions that change the RIP (for
example, branches or calls). A guest user with access
to an I/O or MMIO region could use this flaw to crash
the guest.(CVE-2014-3647i1/4%0
- The __munlock_pagevec function in mm/mlock.c in the
Linux kernel, before 4.11.4, allows local users to
cause a denial of service (NR_MLOCK accounting
corruption) via crafted use of mlockall and munlockall
system calls.(CVE-2017-18221i1/4%0
- ** RESERVED ** This candidate has been reserved by an
organization or individual that will use it when
announcing a new security problem. When the candidate
has been publicized, the details for this candidate
will be provided.(CVE-2018-1120i1/4%0
- The proc_connectinfo() function in
'drivers/usb/core/devio.c' in the Linux kernel through
4.6 does not initialize a certain data structure, which
allows local users to obtain sensitive information from
kernel stack memory via a crafted USBDEVFS_CONNECTINFO
ioctl call. The stack object 'ci' has a total size of 8
bytes. Its last 3 bytes are padding bytes which are not
initialized and are leaked to
userland.(CVE-2016-4482i1/4%0
- A vulnerability was found in the Linux kernel. An
unprivileged local user could trigger oops in
shash_async_export() by attempting to force the
in-kernel hashing algorithms into decrypting an empty
data set.(CVE-2016-8646i1/4%0
- An issue was discovered in the btrfs filesystem code in
the Linux kernel. An invalid NULL pointer dereference
in btrfs_root_node() when mounting a crafted btrfs
image is due to a lack of chunk block group mapping
validation in btrfs_read_block_groups() in the
fs/btrfs/extent-tree.c function and a lack of
empty-tree checks in check_leaf() in
fs/btrfs/tree-checker.c function. This could lead to a
system crash and a denial of service.(CVE-2018-14612i1/4%0
- It was found that the Linux kernel's TCP/IP protocol
suite implementation for IPv6 allowed the Hop Limit
value to be set to a smaller value than the default
one. An attacker on a local network could use this flaw
to prevent systems on that network from sending or
receiving network packets.(CVE-2015-2922i1/4%0
- A NULL-pointer dereference flaw was found in the
kernel, which is caused by a race between revoking a
user-type key and reading from it. The issue could be
triggered by an unprivileged user with a local account,
causing the kernel to crash (denial of
service).(CVE-2015-7550i1/4%0

description block directly from the EulerOS security advisory. Tenable

without introducing additional issues.");
