9.5.2. What’s fixed in 6.1.1

9.5.2.1. Malformed WebSocket handshake messages may have caused a segmentation fault

Web Integration Service’s WebSocket API requires client applications to initiate communication with a HELLO message, which provides all the necessary information to complete a handshake (e.g., content type, protocol version, and API keys). HELLO messages must be encoded as a colon-separated string of name-value pairs (each terminated by a carriage return and line-feed character sequence).

In Web Integration Service 6.1.0, a malformed HELLO message may have caused an unhandled error that lead to a crash in some cases. This issue has been resolved.

[RTI Issue ID WEBINT-208]

9.5.2.2. Race condition when closing WebSocket connection caused a segmentation fault

Web Integration Service’s WebSocket API requires a WebSocket connection. When that connection was bound to one or more data readers, there was a race condition if the connection was closed while Web Integration Service was sending a message to it. This caused the connection to be removed from the service’s memory, followed by a segmentation fault. This issue has been resolved.

[RTI Issue ID WEBINT-208]

9.5.2.3. Fixes related to vulnerabilities

This release fixes some potential vulnerabilities, described below.

9.5.2.3.1. Potential crash in Web Integration Service due to multiple vulnerabilities in SQLite

Previous releases of Web Integration Service had a third-party dependency on SQLite 3.29.0. That version of SQLite is known to be affected by a number of publicly disclosed vulnerabilities.

These vulnerabilities have been fixed by upgrading to the latest stable version of SQLite, 3.37.2. See Third-party software upgrades for details.

The impact on Web Integration Service of using the previous version was as follows:

• Exploitable through a compromised local file system containing malicious SQLite database files.

• Web Integration Service could crash.

• CVSS v3.1 Score: 7.5 HIGH

• CVSS v3.1 Vector: AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H

[RTI Issue ID WEBINT-234]

9.5.3. What’s new in 6.1.0

9.5.3.1. New platforms

Web Integration Service now includes support for these platforms:

• macOS 10.15 (x64)

• Red Hat® Enterprise Linux 7.6 (x64)

• Ubuntu 18.04 LTS (Arm v8)

• Ubuntu 20.04 LTS (x64)

• Yocto Project® 2.5 (Arm v8) (custom-supported target platform)

For more information on these platforms, see the RTI Connext DDS Core Libraries Platform Notes for this release.

9.5.3.2. Removed platforms

These platforms are no longer supported:

• 32-bit Linux and Windows platforms

• macOS 10.12

• SUSE Linux Enterprise Server 11

• Ubuntu 12.04 LTS

9.5.3.3. Support for WebSockets

This release introduces support for WebSockets (WS) and Secure WebSockets (WSS) in Web Integration Service, so it will allow web applications to interact through these protocol in a DDS environment. For more information, see WebSocket API.

9.5.3.4. Upgraded to CivetWeb v1.13

Web Integration Service has upgraded the version of its embedded web server, CivetWeb, to v1.13. For more information on CivetWeb, please see the Release Notes on GitHub: https://github.com/civetweb/civetweb/blob/master/RELEASE_NOTES.md#release-notes-v113.

9.6. Known Issues

9.6.1. Configurations and their applications cannot use same name

Due to current limitations in Connext DDS’s XML Parser, the name of the Web Integration Service configuration tag and the name of the applications within that configuration cannot be the same. For example:

<web_integration_service name="ShapesDemo">
    <application name="ShapesDemo"/>
</web_integration_service>

To workaround this limitation, use different names for the service configuration tag and the applications within. For example:

<web_integration_service name="ShapesDemo">
    <application name="ShapesDemoApplication"/>
</web_integration_service>
