Details

It was discovered that containerd insufficiently restricted permissions on
container root and plugin directories. If a user or automated system were
tricked into launching a specially crafted container image, a remote
attacker could traverse directory contents and modify files and execute
programs on the host file system, possibly leading to privilege escalation.
(CVE-2021-41103)

It was discovered that containerd incorrectly handled file permission
changes. If a user or automated system were tricked into launching a
specially crafted container image, a remote attacker could change
permissions on files on the host file system and possibly escalate
privileges. (CVE-2021-32760)

It was discovered that containerd allows attackers to gain access to read-
only copies of arbitrary files and directories on the host via a specially-
crafted image configuration. An attacker could possibly use this issue to
obtain sensitive information. (CVE-2022-23648)

It was discovered that containerd incorrectly handled certain memory
operations. A remote attacker could use this to cause a denial of service.
(CVE-2022-31030)
