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 SUSE Linux SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2026:0211-1 advisory.

    - CVE-2025-14523: Reject duplicated Host in headers and followed upstream update (bsc#1254876).
    - CVE-2026-0716: Fixed out-of-bounds read for websocket (bsc#1256418)
    - CVE-2026-0719: Fixed overflow for password md4sum (bsc#1256399)

Tenable has extracted the preceding description block directly from the SUSE security advisory.

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