Summary
Pion/DTLS contains buffer for inbound DTLS fragments with no limit
Details

Impact

A buffer that was used for inbound network traffic had no upper limit. Pion DTLS would buffer all network traffic from the remote user until the handshake completes or times out. An attacker could exploit this to cause excessive memory usage.

Patches

Workarounds

No workarounds available, upgrade to Pion DTLS v2.1.4
