"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):ext4_protect_reserved_inode in
fs/ext4/block_validity.c in the Linux kernel through
5.5.3 allows attackers to cause a denial of service
(soft lockup) via a crafted journal
size.(CVE-2020-8992)An issue was discovered in the
Linux kernel through 5.5.6. set_fdc in
drivers/block/floppy.c leads to a wait_til_ready
out-of-bounds read because the FDC index is not checked
for errors before assigning it, aka
CID-2e90ca68b0d2.(CVE-2020-9383)There is a
use-after-free vulnerability in the Linux kernel
through 5.5.2 in the vgacon_invert_region function in
drivers/video/console/vgacon.c.(CVE-2020-8649)There is
a use-after-free vulnerability in the Linux kernel
through 5.5.2 in the vc_do_resize function in
drivers/tty/vt/vt.c.(CVE-2020-8647)Insufficient access
control in subsystem for Intel (R) processor graphics
in 6th, 7th, 8th and 9th Generation Intel(R) Core(TM)
Processor Families Intel(R) Pentium(R) Processor J, N,
Silver and Gold Series Intel(R) Celeron(R) Processor J,
N, G3900 and G4900 Series Intel(R) Atom(R) Processor A
and E3900 Series Intel(R) Xeon(R) Processor E3-1500 v5
and v6 and E-2100 Processor Families may allow an
authenticated user to potentially enable denial of
service via local access.(CVE-2019-0154)There is a
use-after-free vulnerability in the Linux kernel
through 5.5.2 in the n_tty_receive_buf_common function
in drivers/tty_tty.c.(CVE-2020-8648)In the Linux kernel
4.14 longterm through 4.14.165 and 4.19 longterm
through 4.19.96 (and 5.x before 5.2), there is a
use-after-free (write) in the i915_ppgtt_close function
in drivers/gpu/drm/i915/i915_gem_gtt.c, aka
CID-7dc40713618c. This is related to
i915_gem_context_destroy_ioctl in
drivers/gpu/drm/i915/i915_gem_context.c.(CVE-2020-7053)
Insufficient control flow in certain data structures
for some Intel(R) Processors with Intel(R) Processor
Graphics may allow an unauthenticated user to
potentially enable information disclosure via local
access.(CVE-2019-14615)
