There are multiple Curl < v8.1.0 vulnerabilities affecting Windows Server 2019, when will Microsoft release a security update?
There are 4 Curl vulnerabilities as listed below:
CVE-2023-28319: A use after free vulnerability exists in curl <v8.1.0 in the way libcurl offers a feature to verify an SSH server's public key using a SHA 256 hash.
CVE-2023-28321: An improper certificate validation vulnerability exists in curl <v8.1.0 in the way it supports matching of wildcard patterns when listed as "Subject Alternative Name" in TLS server certificates. curl can be built to use its own name matching function for TLS rather than one provided by a TLS library. This private wildcard matching function would match IDN (International Domain Name) hosts incorrectly and could as a result accept patterns that otherwise should mismatch. IDN hostnames are converted to puny code before used for certificate checks. Puny coded names always start with xn--
and should not be allowed to pattern match, but the wildcard check in curl could still check for x*
, which would match even though the IDN name most likely contained nothing even resembling an x
.
CVE-2023-28322: An information disclosure vulnerability exists in curl <v8.1.0 when doing HTTP(S) transfers, libcurl might erroneously use the read callback (CURLOPT_READFUNCTION
) to ask for data to send, even when the CURLOPT_POSTFIELDS
option has been set, if the same handle previously wasused to issue a PUT
request which used that callback.
CVE-2023-28320: A denial of service vulnerability exists in curl <v8.1.0 in the way libcurl provides several different backends for resolving host names, selected at build time.
The current version last updated by Microsoft during the monthly security release was to 8.0.1.0. When will microsoft address these vulnerabilities by updating Curl?
