According to the versions of the c-ares package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - c-ares is an asynchronous resolver library. c-ares is vulnerable to denial of service. If a target     resolver sends a query, the attacker forges a malformed UDP packet with a length of 0 and returns them to     the target resolver. The target resolver erroneously interprets the 0 length as a graceful shutdown of the     connection. This issue has been patched in version 1.19.1. (CVE-2023-32067)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The remote Oracle Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2023-4034 advisory.

  - c-ares is an asynchronous resolver library. When /dev/urandom or RtlGenRandom() are unavailable, c-ares     uses rand() to generate random numbers used for DNS query ids. This is not a CSPRNG, and it is also not     seeded by srand() so will generate predictable output. Input from the random number generator is fed into     a non-compilant RC4 implementation and may not be as strong as the original RC4 implementation. No attempt     is made to look for modern OS-provided CSPRNGs like arc4random() that is widely available. This issue has     been fixed in version 1.19.1. (CVE-2023-31147)

  - c-ares is an asynchronous resolver library. ares_inet_net_pton() is vulnerable to a buffer underflow for     certain ipv6 addresses, in particular 0::00:00:00/2 was found to cause an issue. C-ares only uses this     function internally for configuration purposes which would require an administrator to configure such an     address via ares_set_sortlist(). However, users may externally use ares_inet_net_pton() for other purposes     and thus be vulnerable to more severe issues. This issue has been fixed in 1.19.1. (CVE-2023-31130)

The remote Ubuntu 16.04 ESM / 18.04 ESM host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6164-2 advisory.

    USN-6164-1 fixed several vulnerabilities in c-ares. This update provides the corresponding update for     Ubuntu 16.04 LTS and Ubuntu 18.04 LTS.

    Original advisory details:

    Hannes Moesl discovered that c-ares incorrectly handled certain ipv6

    addresses. An attacker could use this issue to cause c-ares to crash,

    resulting in a denial of service, or possibly execute arbitrary code.

    (CVE-2023-31130)

    Xiang Li discovered that c-ares incorrectly handled certain UDP packets. A

    remote attacker could possibly use this issue to cause c-res to crash,

    resulting in a denial of service. (CVE-2023-32067)

The remote SUSE Linux SLES15 / SLES_SAP15 / openSUSE 15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2023:2669-1 advisory.

  - This affects versions of the package http-cache-semantics before 4.1.1. The issue can be exploited via     malicious request header values sent to a server, when that server reads the cache policy from the request     using this library. (CVE-2022-25881)

  - The vulnerability exists due to the use of proto in process.mainModule.proto.require(). This allows to     bypass the policy mechanism and require modules outside of the policy.json definition. (CVE-2023-30581)

  - The vulnerability exists due to the way Node.js (.msi version) installation process handles a missing     %USERPROFILE% environment variable. If the variable is not set, the .msi installer will try to include a     current working directory into the search path and will libraries in an unsafe manner. A local user can     place a malicious file on the victim's system and execute arbitrary code with elevated privileges.
    (CVE-2023-30585)

  - The vulnerability exists due to insufficient validation of user-supplied public key within the     crypto.X509Certificate() API. A remote user can pass an invalid public key to the application and perform     a denial of service (DoS) attack. (CVE-2023-30588)

  - The llhttp parser in the http module in Node v20.2.0 does not strictly use the CRLF sequence to delimit     HTTP requests. This can lead to HTTP Request Smuggling (HRS). The CR character (without LF) is sufficient     to delimit HTTP header fields in the llhttp parser. According to RFC7230 section 3, only the CRLF sequence     should delimit each header-field. This impacts all Node.js active versions: v16, v18, and, v20     (CVE-2023-30589)

  - The vulnerability exists due to inconsistency between implementation and documented design within the     generateKeys() API function. The documented behavior is different from the actual behavior, and this     difference could lead to security issues in applications that use these APIs as the DiffieHellman may be     used as the basis for application-level security. (CVE-2023-30590)
