In the Linux kernel before 5.2, a setxattr operation, after a mount of a crafted ext4 image, can cause a slab-out-of-bounds write access because of an ext4_xattr_set_entry use-after-free in fs/ext4/xattr.c when a large old_size value is used in a memset call, aka CID-345c0dbf3a30.

CVE-2019-19319 [MEDIUM] Linux kernel vulnerabilities
Title: Linux kernel vulnerabilities
Summary: Several security issues were fixed in the Linux kernel.
It was discovered that the ext4 file system implementation in the Linux
kernel did not properly handle setxattr operations in some situations. A
local attacker could use this to cause a denial of service (system crash)
or possibly execute arbitrary code. (CVE-2019-19319)
It was discovered that memory contents previously stored in
microarchitectural special registers after RDRAND, RDSEED, and SGX EGETKEY
read operations on Intel client and Xeon E3 processors may be briefly
exposed to processes on the same or different processor cores. A local
attacker could use this to expose sensitive information. (CVE-2020-0543)

kernel: out-of-bounds write in ext4_xattr_set_entry in fs/ext4/xattr.c
In the Linux kernel before 5.2, a setxattr operation, after a mount of a crafted ext4 image, can cause a slab-out-of-bounds write access because of an ext4_xattr_set_entry use-after-free in fs/ext4/xattr.c when a large old_size value is used in a memset call, aka CID-345c0dbf3a30.
An out-of-bounds write flaw was found in the Linux kernel’s Ext4 FileSystem in the way it uses a crafted ext4 image. This flaw allows a local user with physical access to crash the system or potentially escalate their privileges on the system.
Statement: This issue is rated as having Moderate impact because of the preconditions needed to trigger the issue (physical access or user interaction to mount the crafted filesystem image).

## Abstract
Container technology, (e.g., Docker) is being widely adopted for deploying software infrastructures or applications in the form of container images.
Security vulnerabilities in the container images are a primary concern for developing containerized software.
Exploitation of the vulnerabilities could result in disastrous impact, such as loss of confidentiality, in
