curl supports chained HTTP compression algorithms, meaning that a server response can be compressed multiple times and potentially with different algorithms. The number of acceptable links in this decompression chain was capped, but the cap was implemented on a per-header basis allowing a malicious server to insert a virtually unlimited number of compression steps simply by using many headers. The use of such a decompression chain could result in a malloc bomb , making curl end up spending enormous amounts of allocated heap memory, or trying to and returning out of memory errors.
