"The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is,
therefore, affected by multiple vulnerabilities as referenced in the TSSA-2024:0660 advisory.

    Package updates are available for TencentOS Server 4 that fix the following vulnerabilities:

    CVE-2024-37298:
    gorilla/schema converts structs to and from form values. Prior to version 1.4.1 Running
    `schema.Decoder.Decode()` on a struct that has a field of type `[]struct{...}` opens it up to malicious
    attacks regarding memory allocations, taking advantage of the sparse slice functionality. Any use of
    `schema.Decoder.Decode()` on a struct with arrays of other structs could be vulnerable to this memory
    exhaustion vulnerability. Version 1.4.1 contains a patch for the issue.

    CVE-2024-3056:
    A flaw was found in Podman. This issue may allow an attacker to create a specially crafted container that,
    when configured to share the same IPC with at least one other container, can create a large number of IPC
    resources in /dev/shm. The malicious container will continue to exhaust resources until it is out-of-
    memory (OOM) killed. While the malicious container's cgroup will be removed, the IPC resources it created
    are not. Those resources are tied to the IPC namespace that will not be removed until all containers using
    it are stopped, and one non-malicious container is holding the namespace open. The malicious container is
    restarted, either automatically or by attacker control, repeating the process and increasing the amount of
    memory consumed. With a container configured to restart always, such as `podman run --restart=always`,
    this can result in a memory-based denial of service of the system.

Tenable has extracted the preceding description block directly from the Tencent Linux security advisory.

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