NVD Description

Note: Versions mentioned in the description apply only to the upstream libsoup-devel package and not the libsoup-devel package as distributed by RHEL. See How to fix? for RHEL:6 relevant fixed versions and status.

A flaw was found in libsoup. A remote attacker, by controlling the method parameter of the soup_message_new() function, could inject arbitrary headers and additional request data. This vulnerability, known as CRLF (Carriage Return Line Feed) injection, occurs because the method value is not properly escaped during request line construction, potentially leading to HTTP request injection.
