AlienVault OTX Malware

node

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)
  })
})
```

The vulnerability CVE-2025-59465 in Node.js involves a malformed HTTP/2 HEADERS frame with oversized or invalid HPACK data that triggers an unhandled TLSSocket error (ECONNRESET). Instead of gracefully closing the connection, this error causes the Node.js process to crash, enabling a remote denial of service condition. This flaw affects applications lacking explicit error handlers on secure sockets. The CVSS v3.0 base score is 7.5 (high severity), reflecting network attack vector, low attack complexity, no privileges required, no user interaction, unchanged scope, no confidentiality or integrity impact, but high availability impact. Red Hat has published multiple advisories and errata providing security updates to fix this issue in their Node.js packages.
