A remote, unauthenticated attacker can exhaust the pool with one spoofed datagram per source and deny DTLS service to legitimate clients until the application resets the sessions.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-770","CWE-772"],"vendors":[],"products":[],"references":[{"url":"https://github.com/eclipse-threadx/netxduo/security/advisories/GHSA-3p2g-x7hh-3w4c","tags":[]},{"url":"https://gitlab.eclipse.org/security/cve-assignment/-/work_items/487","tags":[]}],"exploitRefs":[{"url":"https://github.com/eclipse-threadx/netxduo/security/advisories/GHSA-3p2g-x7hh-3w4c","tags":[]}],"hasPoc":true,"ai":null}
