SIPSorcery is vulnerable to Denial of Service (DoS)
53
Medium Risk
This Affects:
SIPSorceryTL;DR
The WebRTC data channel establishment parser reads label and protocol length fields from an incoming DCEP OPEN message without validating them against the actual message size. A peer can send an OPEN message whose declared lengths exceed the buffer, causing an out-of-range access and an uncaught exception during data channel setup. The fix checks the label and protocol lengths and uses the supplied offsets before decoding the fields.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and you accept WebRTC data channels from untrusted peers.
