Synopsis

The remote Red Hat host is missing one or more security updates for runc.

Description

The remote Redhat Enterprise Linux 9 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2023:6380 advisory.

- runc: integer overflow in netlink bytemsg length field allows attacker to override netlink-based container configuration (CVE-2021-43784)

- golang: crypto/tls: large handshake records may cause panics (CVE-2022-41724)

- runc: Rootless runc makes `/sys/fs/cgroup` writable (CVE-2023-25809)

- runc: volume mount race condition (regression of CVE-2019-19921) (CVE-2023-27561)

- runc: AppArmor can be bypassed when `/proc` inside the container is symlinked with a specific mount configuration (CVE-2023-28642)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL runc package based on the guidance in RHSA-2023:6380.
