Synopsis

The remote SUSE host is missing one or more security updates.

Description

The remote SUSE Linux SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2026:0834-1 advisory.

 - CVE-2025-32049: denial of service attack to websocket server (bsc#1240751).
 - CVE-2026-1467: lack of input sanitization can lead to unintended or unauthorized HTTP requests (bsc#1257398).
 - CVE-2026-1539: proxy authentication credentials leaked via the Proxy-Authorization header when handling HTTP redirects (bsc#1257441).
 - CVE-2026-1760: improper handling of HTTP requests combining certain headers by SoupServer can lead to HTTP request smuggling and potential DoS (bsc#1257597).
 - CVE-2026-2369: buffer overread due to integer underflow when handling zero-length resources (bsc#1258120).
 - CVE-2026-2443: out-of-bounds read when processing specially crafted HTTP Range headers can lead to heap information disclosure to remote attackers (bsc#1258170).
 - CVE-2026-2708: HTTP request smuggling via duplicate Content-Length headers (bsc#1258508).

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.

Solution

Update the affected libsoup-2_4-1, libsoup2-devel, libsoup2-lang and / or typelib-1_0-Soup-2_4 packages.
