An integer underflow vulnerability exists in the function in of gpsd versions prior to commit . When parsing a NAVCOM packet, the payload length is calculated using without checking if the input byte is less than 4. This results in an unsigned integer underflow, setting to a very large value (near ). The parser then enters a loop attempting to consume this massive number of bytes, causing 100% CPU utilization and a Denial of Service (DoS) condition.
