Description

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.
