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

  - runc is a CLI tool for spawning and running containers on Linux according to the OCI specification. In     runc, netlink is used internally as a serialization system for specifying the relevant container     configuration to the `C` portion of the code (responsible for the based namespace setup of containers). In     all versions of runc prior to 1.0.3, the encoder did not handle the possibility of an integer overflow in     the 16-bit length field for the byte array attribute type, meaning that a large enough malicious byte     array attribute could result in the length overflowing and the attribute contents being parsed as netlink     messages for container configuration. This vulnerability requires the attacker to have some control over     the configuration of the container and would allow the attacker to bypass the namespace restrictions of     the container by simply adding their own netlink payload which disables all namespaces. The main users     impacted are those who allow untrusted images with untrusted configurations to run on their machines (such     as with shared cloud infrastructure). runc version 1.0.3 contains a fix for this bug. As a workaround, one     may try disallowing untrusted namespace paths from your container. It should be noted that untrusted     namespace paths would allow the attacker to disable namespace protections entirely even in the absence of     this bug. (CVE-2021-43784)

  - runc through 1.1.4 has Incorrect Access Control leading to Escalation of Privileges, related to     libcontainer/rootfs_linux.go. To exploit this, an attacker must be able to spawn two containers with     custom volume-mount configurations, and be able to run custom images. NOTE: this issue exists because of a     CVE-2019-19921 regression. (CVE-2023-27561)

  - runc is a CLI tool for spawning and running containers according to the OCI specification. It was found     that AppArmor can be bypassed when `/proc` inside the container is symlinked with a specific mount     configuration. This issue has been fixed in runc version 1.1.5, by prohibiting symlinked `/proc`. See PR     #3785 for details. users are advised to upgrade. Users unable to upgrade should avoid using an untrusted     container image. (CVE-2023-28642)

  - runc is a CLI tool for spawning and running containers according to the OCI specification. In affected     versions it was found that rootless runc makes `/sys/fs/cgroup` writable in following conditons: 1. when     runc is executed inside the user namespace, and the `config.json` does not specify the cgroup namespace to     be unshared (e.g.., `(docker|podman|nerdctl) run --cgroupns=host`, with Rootless Docker/Podman/nerdctl) or     2. when runc is executed outside the user namespace, and `/sys` is mounted with `rbind, ro` (e.g., `runc     spec --rootless`; this condition is very rare). A container may gain the write access to user-owned cgroup     hierarchy `/sys/fs/cgroup/user.slice/...` on the host . Other users's cgroup hierarchies are not affected.
    Users are advised to upgrade to version 1.1.5. Users unable to upgrade may unshare the cgroup namespace     (`(docker|podman|nerdctl) run --cgroupns=private)`. This is the default behavior of Docker/Podman/nerdctl     on cgroup v2 hosts. or add `/sys/fs/cgroup` to `maskedPaths`. (CVE-2023-25809)

  - Large handshake records may cause panics in crypto/tls. Both clients and servers may send large TLS     handshake records which cause servers and clients, respectively, to panic when attempting to construct     responses. This affects all TLS 1.3 clients, TLS 1.2 clients which explicitly enable session resumption     (by setting Config.ClientSessionCache to a non-nil value), and TLS 1.3 servers which request client     certificates (by setting Config.ClientAuth >= RequestClientCert). (CVE-2022-41724)

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