| CVE-2021-22926 | 5 Haxx, Netapp, Oracle and 2 more | 26 Curl, Active Iq Unified Manager, Clustered Data Ontap and 23 more | 2024-03-27 | 5.0 MEDIUM | 7.5 HIGH |
| libcurl-using applications can ask for a specific client certificate to be used in a transfer. This is done with the `CURLOPT_SSLCERT` option (`--cert` with the command line tool).When libcurl is built to use the macOS native TLS library Secure Transport, an application can ask for the client certificate by name or with a file name - using the same option. If the name exists as a file, it will be used instead of by name.If the appliction runs with a current working directory that is writable by other users (like `/tmp`), a malicious user can create a file name with the same name as the app wants to use by name, and thereby trick the application to use the file based cert instead of the one referred to by name making libcurl send the wrong client certificate in the TLS connection handshake. | |||||

| When sending data to an MQTT server, libcurl <= 7.73.0 and 7.78.0 could in some circumstances erroneously keep a pointer to an already freed memory area and both use that again in a subsequent call to send data and also free it *again*. | |||||

| When curl >= 7.20.0 and <= 7.78.0 connects to an IMAP or POP3 server to retrieve data using STARTTLS to upgrade to TLS security, the server can respond and send back multiple responses at once that curl caches. curl would then upgrade to TLS but not flush the in-queue of cached responses but instead continue using and trustingthe responses it got *before* the TLS handshake as if they were authenticated.Using this flaw, it allows a Man-In-The-Middle attacker to first inject the fake responses, then pass-through the TLS traffic from the legitimate server and trick curl into sending data back to the user thinking the attacker's injected data comes from the TLS-protected server. | |||||

| An improper authentication vulnerability exists in curl 7.33.0 to and including 7.82.0 which might allow reuse OAUTH2-authenticated connections without properly making sure that the connection was authenticated with the same credentials as set for this transfer. This affects SASL-enabled protocols: SMPTP(S), IMAP(S), POP3(S) and LDAP(S) (openldap only). | |||||

| CVE-2022-27779 | 3 Haxx, Netapp, Splunk | 15 Curl, Clustered Data Ontap, H300s and 12 more | 2024-03-27 | 5.0 MEDIUM | 5.3 MEDIUM |
| libcurl wrongly allows cookies to be set for Top Level Domains (TLDs) if thehost name is provided with a trailing dot.curl can be told to receive and send cookies. curl's "cookie engine" can bebuilt with or without [Public Suffix List](https://publicsuffix.org/)awareness. If PSL support not provided, a more rudimentary check exists to atleast prevent cookies from being set on TLDs. This check was broken if thehost name in the URL uses a trailing dot.This can allow arbitrary sites to set cookies that then would get sent to adifferent and unrelated site or domain. | |||||

| libcurl provides the `CURLOPT_CERTINFO` option to allow applications torequest details to be returned about a server's certificate chain.Due to an erroneous function, a malicious server could make libcurl built withNSS get stuck in a never-ending busy-loop when trying to retrieve thatinformation. | |||||
| CVE-2022-30115 | 3 Haxx, Netapp, Splunk | 15 Curl, Clustered Data Ontap, H300s and 12 more | 2024-03-27 | 4.0 MEDIUM | 4.3 MEDIUM |
| Using its HSTS support, curl can be instructed to use HTTPS directly insteadof using an insecure clear-text HTTP step even when HTTP is provided in theURL. This mechanism could be bypassed if the host name in the given URL used atrailing dot while not using one when it built the HSTS cache. Or the otherway around - by having the trailing dot in the HSTS cache and *not* using thetrailing dot in the URL. | |||||
| CVE-2022-32205 | 7 Apple, Debian, Fedoraproject and 4 more | 29 Macos, Debian Linux, Fedora and 26 more | 2024-03-27 | 4.3 MEDIUM | 4.3 MEDIUM |
| 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. | |||||
| CVE-2022-32206 | 6 Debian, Fedoraproject, Haxx and 3 more | 30 Debian Linux, Fedora, Curl and 27 more | 2024-03-27 | 4.3 MEDIUM | 6.5 MEDIUM |
| 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. | |||||
| CVE-2022-32207 | 6 Apple, Debian, Fedoraproject and 3 more | 19 Macos, Debian Linux, Fedora and 16 more | 2024-03-27 | 7.5 HIGH | 9.8 CRITICAL |
| When curl < 7.84.0 saves cookies, alt-svc and hsts data to local files, it makes the operation atomic by finalizing the operation with a rename from a temporary name to the final target file name.In that rename operation, it might accidentally *widen* the permissions for the target file, leaving the updated file accessible to more users than intended. | |||||
| CVE-2022-32208 | 6 Apple, Debian, Fedoraproject and 3 more | 19 Macos, Debian Linux, Fedora and 16 more | 2024-03-27 | 4.3 MEDIUM | 5.9 MEDIUM |
| When curl < 7.84.0 does FTP transfers secured by krb5, it handles message verification failures wrongly. This flaw makes it possible for a Man-In-The-Middle attack to go unnoticed and even allows it to inject data to the client. | |||||
| CVE-2022-35252 | 5 Apple, Debian, Haxx and 2 more | 18 Macos, Debian Linux, Curl and 15 more | 2024-03-27 | N/A | 3.7 LOW |
| When curl is used to retrieve and parse cookies from a HTTP(S) server, itaccepts cookies using control codes that when later are sent back to a HTTPserver might make the server return 400 responses. Effectively allowing a"sister site" to deny service to all siblings. | |||||
| CVE-2022-32221 | 5 Apple, Debian, Haxx and 2 more | 13 Macos, Debian Linux, Curl and 10 more | 2024-03-27 | N/A | 9.8 CRITICAL |
| 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 was used to issue a `PUT` request which used that callback. This flaw may surprise the application and cause it to misbehave and either send off the wrong data or use memory after free or similar in the subsequent `POST` request. The problem exists in the logic for a reused handle when it is changed from a PUT to a POST. | |||||
| CVE-2022-35260 | 4 Apple, Haxx, Netapp and 1 more | 12 Macos, Curl, Clustered Data Ontap and 9 more | 2024-03-27 | N/A | 6.5 MEDIUM |
| curl can be told to parse a `.netrc` file for credentials. If that file endsin a line with 4095 consecutive non-white space letters and no newline, curlwould first read past the end of the stack-based buffer, and if the readworks, write a zero byte beyond its boundary.This will in most cases cause a segfault or similar, but circumstances might also cause different outcomes.If a malicious user can provide a custom netrc file to an application or otherwise affect its contents, this flaw could be used as denial-of-service. | |||||
| CVE-2022-42915 | 5 Apple, Fedoraproject, Haxx and 2 more | 13 Macos, Fedora, Curl and 10 more | 2024-03-27 | N/A | 8.1 HIGH |
| curl before 7.86.0 has a double free. If curl is told to use an HTTP proxy for a transfer with a non-HTTP(S) URL, it sets up the connection to the remote server by issuing a CONNECT request to the proxy, and then tunnels the rest of the protocol through. An HTTP proxy might refuse this request (HTTP proxies often only allow outgoing connections to specific port numbers, like 443 for HTTPS) and instead return a non-200 status code to the client. Due to flaws in the error/cleanup handling, this could trigger a double free in curl if one of the following schemes were used in the URL for the transfer: dict, gopher, gophers, ldap, ldaps, rtmp, rtmps, or telnet. The earliest affected version is 7.77.0. | |||||
| CVE-2023-23914 | 3 Haxx, Netapp, Splunk | 12 Curl, Active Iq Unified Manager, Clustered Data Ontap and 9 more | 2024-03-27 | N/A | 9.1 CRITICAL |
| A cleartext transmission of sensitive information vulnerability exists in curl <v7.88.0 that could cause HSTS functionality fail when multiple URLs are requested serially. Using its HSTS support, curl can be instructed to use HTTPS instead of usingan insecure clear-text HTTP step even when HTTP is provided in the URL. ThisHSTS mechanism would however surprisingly be ignored by subsequent transferswhen done on the same command line because the state would not be properlycarried on. | |||||
