VulniPulse record published
Summary
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.
Red Hat severity: Moderate — CVSS 5.3 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L). Weakness: CWE-1050.
