CVE-2022-32206

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.
