Description

In Eclipse Vert.x versions [4.0.0, 4.5.34] or [5.0.0,5.0.12] or [5.1.0,5.1.9] or [5.2.0, 5.2.0], the WebSocket implementation does not define a maximum number of bytes allocation when decompressing frames or messages. This can be used to implement DDOS attacks with a zip bomb. The impacted component is io.vertx:vertx-core.

Affected configurations

• eclipse vert.x (>= 4.5.0 < 4.5.35) • eclipse vert.x (>= 5.0.0 < 5.1.10) • eclipse vert.x 5.2.0
