CVE-2022-32205

A malicious server can serve excessive amounts of Set-Cookie: headers in
a HTTP response to curl and curl < 7.84.0 stores all of them. A
sufficiently large amount of (big) cookies make subsequent HTTP requests to
this, or other servers to which the cookies match, create requests that
become larger than the threshold that curl uses internally to avoid sending
crazy large requests (1048576 bytes) and instead returns an error.This
denial state might remain for as long as the same cookies are kept, match
and haven’t expired. Due to cookie matching rules, a server on
foo.example.com can set cookies that also would match for
bar.example.com, making it it possible for a “sister server” to
effectively cause a denial of service for a sibling site on the same second
level domain using this method.
