vertx-stomp is vulnerable to Denial of Service (DoS)
75
CVE Score
High
Denial of Service (DoS)
TL;DR
FrameParser in vertx-stomp builds a RecordParser with no maximum record size. A peer that sends bytes and never sends a newline makes the parser keep the whole stream in memory, on the server before or after authentication and on a client connected to that peer. The process runs out of heap and crashes. The fix sets a maximum line length on that parser.
How do I fix this?
Upgrade the io.vertx:vertx-stomp library to the patch version.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and the application accepts STOMP connections or connects to a STOMP peer.
