CVE-2025-32907: Libsoup: denial of service in server when client requests a large amount of overlapping ranges with range header
First published: Mon Apr 14 2025(Updated: )
A flaw was found in libsoup. The implementation of HTTP range requests is vulnerable to a resource consumption attack. This flaw allows a malicious client to request the same range many times in a single HTTP request, causing the server to use large amounts of memory. This does not allow for a full denial of service.
