Synopsis

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.

Security Fix(es):

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

* 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)

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