Insight

The flaw is due to a crafted or malformed STANAG 4607 capture file will cause an infinite loop and memory exhaustion. If the packet size field in a packet header is null, the offset to read from will not advance, causing continuous attempts to read the same zero length packet. This will quickly exhaust all system memory.
