The version of c-ares installed on the remote host is prior to 1.10.0-3. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2024-2494 advisory.

    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)

According to its self-reported version, the Nessus Network Monitor running on the remote host is prior to 6.4.0. It is, therefore, affected by multiple vulnerabilities as referenced in the TNS-2024-07 advisory.

  - Nessus Network Monitor leverages third-party software to help provide underlying functionality. Several of     the third-party components (hyperscan, curl and c-ares)were found to contain vulnerabilities, and     updated versions have been made available by the providers.Out of caution and in line with best practice,     Tenable has opted to upgrade these components to address the potential impact of the issues. Nessus     Network Monitor 6.4.0 updates hyperscan to version 5.4.2, curl to version 8.6.0, and c-ares to version     1.28.0. Tenable has released Nessus Network Monitor 6.4.0 to address these issues. The installation files     can be obtained from the Tenable Downloads Portal (https://www.tenable.com/downloads/nessus-network-     monitor). (CVE-2023-28711, CVE-2023-46218, CVE-2023-46219, CVE-2024-25629)

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

The version of the Tenable Identity Exposure running on the remote host is prior to 3.77.9. It is, therefore, affected by multiple vulnerabilities according to advisory TNS-2025-01, including the following:

  - libcurl would wrongly close the same eventfd file descriptor twice when taking down a connection channel     after having completed a threaded name resolve. (CVE-2025-0665)

  - With the aid of the diagnostics_channel utility, an event can be hooked into whenever a worker thread     is created. This is not limited only to workers but also exposes internal workers, where an instance     of them can be fetched, and its constructor can be grabbed and reinstated for malicious usage. This     vulnerability affects Permission Model users (--permission) on Node.js v20, v22, and v23. (CVE-2025-23083)

  - When libcurl is asked to perform automatic gzip decompression of content-encoded HTTP responses with     the CURLOPT_ACCEPT_ENCODING option, **using zlib 1.2.0.3 or older**, an attacker-controlled integer     overflow would make libcurl perform a buffer overflow. (CVE-2025-0725)

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

The remote Rocky Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RLSA-2024:2778 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)
