AI-suggested
Red Hat has released security updates addressing CVE-2025-59465 in their Node.js packages. Applying these official patches is the recommended remediation. Users should update to the fixed versions provided by Red Hat as detailed in their advisories. Additionally, applications should implement explicit error handlers on secure sockets to prevent unhandled exceptions leading to crashes. Patch status is confirmed by Red Hat advisories; therefore, applying the vendor-provided updates is the primary mitigation.
Description
A malformed `HTTP/2 HEADERS` frame with oversized, invalid `HPACK` data can cause Node.js to crash by triggering an unhandled `TLSSocket` error `ECONNRESET`. Instead of safely closing the connection, the process crashes, enabling a remote denial of service. This primarily affects applications that do not attach explicit error handlers to secure sockets, for example: ``` server.on('secureConnection', socket => { socket.on('error', err => { console.log(err) }) }) ```
