Description

GNOME libsoup before 3.6.0 allows HTTP request smuggling in some configurations because '\0' characters at the end of header names are ignored, i.e., a "Transfer-Encoding\0: chunked" header is treated the same as a "Transfer-Encoding: chunked" header.

Affected products

• GNOME libsoup: before 3.6.0 — fixed in 3.6.0

How to fix

Upgrade to a fixed version: GNOME libsoup 3.6.0. Check the vendor advisory for mitigations.
