Description

This security bulletin contains information about 1 security vulnerability.


1) UNIX symbolic link following (CVE-ID: CVE-2019-18466)

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a symlink following issue in libpod (podman) in the host context during a copy operation from the container to the host, because an undesired glob operation occurs. An attacker could create a container image containing particular symlinks that, when copied by a victim user to the host filesystem, may overwrite existing files with others from the host.

Successful exploitation of this vulnerability may result in privilege escalation on the host operating system.
