Improper Handling of Highly Compressed Data (Data Amplification)

BaseIncomplete

The product does not handle or incorrectly handles a compressed input with a very high compression ratio that produces a large output.

An example of data amplification is a "decompression bomb," a small ZIP file that can produce a large amount of data when it is decompressed.
