NVD Description

Note: Versions mentioned in the description apply only to the upstream openshift-clients package and not the openshift-clients package as distributed by RHEL. See How to fix? for RHEL:9 relevant fixed versions and status.

A flaw was found in CRI-O. The fix for a previous vulnerability (CVE-2022-4318) was incorrect, allowing it to be bypassed. An attacker capable of setting environment variables on a container can inject a newline character into the HOME environment variable. This issue allows the addition of arbitrary lines into /etc/passwd by use of a specially crafted environment variable.
