Related CVEs:
- CVE-2022-32206: A vulnerability was found in curl. This issue occurs because the number of acceptable “links” in the “decompression chain” was unbounded, allowing a malicious server to insert a virtually unlimited number of compression steps. This flaw leads to a denial of service, either by mistake or by a malicious actor.
- CVE-2023-23916: A flaw was found in the Curl package. A malicious server can insert an unlimited number of compression steps. This decompression chain could result in out-of-memory errors.

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.
