Stack-based buffer overflow in Namazu before 2.0.20 allows remote attackers to cause a denial of service (daemon crash) or possibly execute arbitrary code via a crafted request containing an empty uri field.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
