"The remote Redhat Enterprise Linux 10 host has packages installed that are affected by a vulnerability as referenced in
the RHSA-2025:23437 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.

    Security Fix(es):

    * libsoup: Heap Use-After-Free in libsoup message queue handling during HTTP/2 read completion
    (CVE-2025-12105)

    For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and
    other related information, refer to the CVE page(s) listed in the References section.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

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