The remote Alibaba Cloud Linux 3 host has packages installed that are affected by multiple vulnerabilities as referenced in the ALINUX3-SA-2026:0037 advisory.

    Package updates are available for Alibaba Cloud Linux 3 that fix the following vulnerabilities:

    CVE-2025-14523:
    A flaw in libsoups HTTP header handling allows multiple Host: headers in a request and returns the last     occurrence for server-side processing. Common front proxies often honor the first Host: header, so this     mismatch can cause vhost confusion where a proxy routes a request to one backend but the backend     interprets it as destined for another host. This discrepancy enables request-smuggling style attacks,     cache poisoning, or bypassing host-based access controls when an attacker supplies duplicate Host headers.

    CVE-2026-0719:
    A flaw was identified in the NTLM authentication handling of the libsoup HTTP library, used by GNOME and     other applications for network communication. When processing extremely long passwords, an internal size     calculation can overflow due to improper use of signed integers. This results in incorrect memory     allocation on the stack, followed by unsafe memory copying. As a result, applications using libsoup may     crash unexpectedly, creating a denial-of-service risk.

    CVE-2026-1761:
    A flaw was found in libsoup. This stack-based buffer overflow vulnerability occurs during the parsing of     multipart HTTP responses due to an incorrect length calculation. A remote attacker can exploit this by     sending a specially crafted multipart HTTP response, which can lead to memory corruption. This issue may     result in application crashes or arbitrary code execution in applications that process untrusted server     responses, and it does not require authentication or user interaction.

Tenable has extracted the preceding description block directly from the Alibaba Cloud 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.
