The remote Redhat Enterprise Linux 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2026:2182 advisory.

    Libsoup is an HTTP library implementation in C. It was originally part of a SOAP (Simple Object Access     Protocol) implementation called Soup, but the SOAP and non-SOAP parts have now been split into separate     packages.  libsoup uses the Glib main loop and is designed to work well with GTK applications. This     enables GNOME applications to access HTTP servers on the network in a completely asynchronous fashion,     very similar to the Gtk+ programming model (a synchronous operation mode is also supported for those who     want it), but the SOAP parts were removed long ago.

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

  - 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.

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.
