curl < 7.84.0 supports "chained" HTTP compression algorithms meaning that a serverresponse can be compressed multiple times and potentially with different algorithms. The number of acceptable "links" in this "decompression chain" was unbounded allowing a malicious server to insert a virtually unlimited number of compression steps.The use of such a decompression chain could result in a "malloc bomb" makingcurl end up spending enormous amounts of allocated heap memory or trying toand returning out of memory errors.
