According to the versions of the libuv package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

    libuv is a multi-platform support library with a focus on asynchronous I/O. The `uv_getaddrinfo` function     in `src/unix/getaddrinfo.c` (and its windows counterpart `src/win/getaddrinfo.c`), truncates hostnames to     256 characters before calling `getaddrinfo`. This behavior can be exploited to create addresses like     `0x00007f000001`, which are considered valid by `getaddrinfo` and could allow an attacker to craft     payloads that resolve to unintended IP addresses, bypassing developer checks. The vulnerability arises due     to how the `hostname_ascii` variable (with a length of 256 bytes) is handled in `uv_getaddrinfo` and     subsequently in `uv__idna_toascii`. When the hostname exceeds 256 characters, it gets truncated without a     terminating null byte. As a result attackers may be able to access internal APIs or for websites (similar     to MySpace) that allows users to have `username.example.com` pages. Internal services that crawl or cache     these user pages can be exposed to SSRF attacks if a malicious user chooses a long vulnerable username.
    This issue has been addressed in release version 1.48.0. Users are advised to upgrade. There are no known     workarounds for this vulnerability.(CVE-2024-24806)

Tenable has extracted the preceding description block directly from the EulerOS Virtualization libuv security advisory.

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

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

The remote SUSE Linux SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2024:0732-1 advisory.

  - A vulnerability in the privateDecrypt() API of the crypto library, allowed a covert timing side-channel     during PKCS#1 v1.5 padding error handling. The vulnerability revealed significant timing differences in     decryption for valid and invalid ciphertexts. This poses a serious threat as attackers could remotely     exploit the vulnerability to decrypt captured RSA ciphertexts or forge signatures, especially in scenarios     involving API endpoints processing Json Web Encryption messages. Impacts: Thank you, to hkario for     reporting this vulnerability and thank you Michael Dawson for fixing it. (CVE-2023-46809)

  - A vulnerability in Node.js HTTP servers allows an attacker to send a specially crafted HTTP request with     chunked encoding, leading to resource exhaustion and denial of service (DoS). The server reads an     unbounded number of bytes from a single connection, exploiting the lack of limitations on chunk extension     bytes. The issue can cause CPU and network bandwidth exhaustion, bypassing standard safeguards like     timeouts and body size limits. (CVE-2024-22019)

  - Node.js reports: Code injection and privilege escalation through Linux capabilities- (High) http: Reading     unprocessed HTTP request with unbounded chunk extension allows DoS attacks- (High) Path traversal by     monkey-patching Buffer internals- (High) setuid() does not drop all privileges due to io_uring - (High)     Node.js is vulnerable to the Marvin Attack (timing variant of the Bleichenbacher attack against PKCS#1     v1.5 padding) - (Medium) Multiple permission model bypasses due to improper path traversal sequence     sanitization - (Medium) Improper handling of wildcards in --allow-fs-read and --allow-fs-write (Medium)     Denial of Service by resource exhaustion in fetch() brotli decoding - (Medium) (CVE-2024-22025)
