CVEID:CVE-2021-20206
**DESCRIPTION:**containernetworking cni could allow a remote authenticated attacker to traverse directories on the system. An attacker could load a specially-crafted network configuration containing “dot dot” sequences (/…/) in the ‘type’ field to execute arbitrary files on the system.
CVSS Base score: 7.2

CVEID:CVE-2022-23648
**DESCRIPTION:**containerd could allow a remote attacker to obtain sensitive information, caused by a flaw in the CRI implementation. By using a specially-crafted image configuration, an attacker could exploit this vulnerability to access to read-only copies of arbitrary files and directories on the host system, and use this information to launch further attacks against the affected system.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/220823 for the current score.

CVEID:CVE-2021-32760
**DESCRIPTION:**Containerd could allow a remote attacker to gain elevated privileges on the system, caused by improper file permissions. By pulling and extracting a specially-crafted container image, an attacker could exploit this vulnerability to perform Unix file permission changes for existing files in the host’s filesystem.
