Fedora 41: libsoup3 Important Denial of Service Fix FEDORA-2025-1f41505af2

fedora
Calendar Grey August 7, 2025
Dist Fedora Esm H88
Debian 12 upgrades libcurl addressing serious vulnerabilities, including potential remote code execution threats for improved system stability.
This update fixes these CVEs: CVE-2025-4948 CVE-2025-32908 CVE-2025-32907 CVE-2025-4969

Summary

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.
