Fixed In Version: curl 7.84.0
Doc Type: If docs needed, set a value
Doc Text:
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.
