Multiple Integer underflows in the geonet_print function in tcpdump 4.5.0 through 4.6.2, when in verbose mode, allow remote attackers to cause a denial of service (segmentation fault and crash) via a crafted length value in a Geonet frame.
Weakness
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.
