SIPSorcery is vulnerable to Denial of Service (DoS)

Medium Risk
This Affects:
SIPSorceryTL;DR
The SRTP receiver updates its replay window and rollover counter before AES-GCM authentication completes. Because the state is advanced during decryption rather than after successful authentication, unauthenticated packets carrying forged sequence numbers can move the receiver replay state forward. Subsequent legitimate packets are then discarded as replays, denying the media stream. The fix separates read-only replay checking from state updates so the window and counter change only after a packet authenticates successfully.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and you receive SRTP AES-GCM protected media from untrusted network peers.
Background info
