NVD Description

Note: Versions mentioned in the description apply only to the upstream openshift4/ose-ansible-rhel9-operator package and not the openshift4/ose-ansible-rhel9-operator package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

A flaw was found in ansible-core. When installing a collection with ansible-galaxy collection install, the archive extractor validates member paths using lexical path normalisation (os.path.abspath) instead of resolving symbolic links (os.path.realpath), and it performs no containment check on symlink-typed directory members before creating them. A crafted collection tarball can chain symlink directory entries so that a subsequent file member is written outside the intended destination directory. This allows an attacker who can get a victim to install a malicious collection to overwrite arbitrary files with the privileges of the user running ansible-galaxy, leading to code execution on the control node. This is a bypass of the fix for CVE-2020-10691.
