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.

Security Fix(es):

A vulnerability was found in curl. This issue occurs because it mishandles message verification failures when curl does FTP transfers secured by krb5. This flaw makes it possible for a Man-in-the-middle attack to go unnoticed and allows data injection into the client.(CVE-2022-32208)

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-2022-32206)

A vulnerability was found in curl. This issue occurs because when curl saves cookies, alt-svc, and HSTS data to local files, it makes the operation atomic by finalizing the process with a rename from a temporary name to the final target file name. This flaw leads to unpreserved file permissions, either by mistake or by a malicious actor.(CVE-2022-32207)

A vulnerability was found in curl. This issue occurs because a malicious server can serve excessive amounts of Set-Cookie: headers in an HTTP response to curl, which stores all of them. This flaw leads to a denial of service, either by mistake or by a malicious actor.(CVE-2022-32205)

The curl packages provide the libcurl library and the curl utility for downloading files from servers using various protocols, including HTTP, FTP, and LDAP.
