RHEL 10 : libsoup3 (RHSA-2025:19720)

low Nessus Plugin ID 272286

Language:

Synopsis

The remote Red Hat host is missing a security update for libsoup3.

Description

The remote Redhat Enterprise Linux 10 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2025:19720 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: Integer Overflow in Cookie Expiration Date Handling in libsoup (CVE-2025-4945)

 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.

Solution

Update the RHEL libsoup3 package based on the guidance in RHSA-2025:19720.
