Envoy is a cloud-native, open source edge and service proxy. There is a crash at QuicheDataReader::PeekVarInt62Length(). It is caused by integer underflow in the QuicStreamSequencerBuffer::PeekRegion() implementation.
The product subtracts one value from another, such that the result is less than the minimum allowable integer value, which produces a value that is not equal to the correct result.
