DescriptionCVE.org

Forge (also called node-forge) is a native implementation of Transport Layer Security in JavaScript. Prior to 1.4.3, a forge.tls client accepts a ServerHello compression_method that it did not offer. When the client later handles ServerHelloDone, tls.createConnectionState() rejects the unsupported compression algorithm by throwing an Error that propagates from connection.process(). A malicious server or an on-path attacker can alter the unauthenticated ServerHello compression byte before the server Finished message and terminate a Node.js process when the application does not catch the exception. The affected client paths include direct forge.tls use, forge.tls.wrapSocket, and forge.http; forge.tls servers are not affected, and the issue has no confidentiality or integrity impact. This issue is fixed in version 1.4.3.
