Summary

Red Hat Security Advisory: libsoup security update

Severity

Important

Notes

Topic: An update for libsoup is now available for Red Hat Enterprise Linux 9. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

Details: The libsoup packages provide an HTTP client and server library for GNOME. Security Fix(es): * libsoup: infinite loop while reading websocket data (CVE-2024-52532) * libsoup: HTTP request smuggling via stripping null bytes from the ends of header names (CVE-2024-52530) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

CVE-2024-52530

A flaw was found in the Libsoup library. When Libsoup parses HTTP headers, it ignores null bytes at the end of header names. Thus, `Transfer-Encoding: chunked` is equivalent to `Transfer-Encoding\x00: chunked`. This issue allows request smuggling when Libsoup is used in a service behind a reverse proxy that forwards null bytes without stripping them.

7.5 (High)

Threats

Impact Important

CVE-2024-52532

A flaw was found in Libsoup. The soup_websocket_connection_read function uses a loop that reads incoming WebSocket data via the glib library. This issue makes it possible to cause the loop to run indefinitely by sending a continuous stream of data to it. The effect will prevent the DCV service from accepting any further connections, leading to a denial of service.

7.5 (High)

CVE-2024-52530 (GCVE-0-2024-52530)

Vulnerability from cvelistv5 – Published: 2024-11-11 00:00 – Updated: 2025-11-03 22:28

Summary

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.

Severity

7.5 (High)
