RTI Connext DDS Professional, Connext DDS Secure versions 4.2x to 6.1.0, and Connext DDS Micro versions 2.4 and later are vulnerable when an attacker sends a specially crafted packet to flood target devices with unwanted traffic. This may result in a denial-of-service condition and information exposure.
