The remote AlmaLinux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the ALSA-2024:2780 advisory.

  - A vulnerability in Node.js has been identified, allowing for a Denial of Service (DoS) attack through     resource exhaustion when using the fetch() function to retrieve content from an untrusted URL. The     vulnerability stems from the fact that the fetch() function in Node.js always decodes Brotli, making it     possible for an attacker to cause resource exhaustion when fetching content from an untrusted URL. An     attacker controlling the URL passed into fetch() can exploit this vulnerability to exhaust memory,     potentially leading to process termination, depending on the system configuration. (CVE-2024-22025)

  - c-ares is a C library for asynchronous DNS requests. `ares__read_line()` is used to parse local     configuration files such as `/etc/resolv.conf`, `/etc/nsswitch.conf`, the `HOSTALIASES` file, and if using     a c-ares version prior to 1.27.0, the `/etc/hosts` file. If any of these configuration files has an     embedded `NULL` character as the first character in a new line, it can lead to attempting to read memory     prior to the start of the given buffer which may result in a crash. This issue is fixed in c-ares 1.27.0.
    No known workarounds exist. (CVE-2024-25629)

  - The team has identified a critical vulnerability in the http server of the most recent version of Node,     where malformed headers can lead to HTTP request smuggling. Specifically, if a space is placed before a     content-length header, it is not interpreted correctly, enabling attackers to smuggle in a second request     within the body of the first. (CVE-2024-27982)

  - An attacker can make the Node.js HTTP/2 server completely unavailable by sending a small amount of HTTP/2     frames packets with a few HTTP/2 frames inside. It is possible to leave some data in nghttp2 memory after     reset when headers with HTTP/2 CONTINUATION frame are sent to the server and then a TCP connection is     abruptly closed by the client triggering the Http2Session destructor while header frames are still being     processed (and stored in memory) causing a race condition. (CVE-2024-27983)

  - nghttp2 is an implementation of the Hypertext Transfer Protocol version 2 in C. The nghttp2 library prior     to version 1.61.0 keeps reading the unbounded number of HTTP/2 CONTINUATION frames even after a stream is     reset to keep HPACK context in sync. This causes excessive CPU usage to decode HPACK stream. nghttp2     v1.61.0 mitigates this vulnerability by limiting the number of CONTINUATION frames it accepts per stream.
    There is no workaround for this vulnerability. (CVE-2024-28182)

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