Pion Interceptor's improper RTP padding handling allows remote crash for SFU users (DoS)
Summary
Pion Interceptor's improper RTP padding handling allows remote crash for SFU users (DoS)
Original description
The description as published by the source.
Pion Interceptor is a framework for building RTP/RTCP communication software. Versions v0.1.36 through v0.1.38 contain a bug in a RTP packet factory that can be exploited to trigger a panic with Pion based SFU via crafted RTP packets, This only affect users that use pion/interceptor. Users should upgrade to v0.1.39 or later, which validates that: padLen > 0 && padLen <= payloadLength and return error on overflow, avoiding panic. If upgrading is not possible, apply the patch from the pull request manually or drop packets whose P-bit is set but whose padLen is zero or larger than the remaining payload.
