2023-05-26 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. If it is built to use the synchronous resolver, it allows name resolves to time-out slow operations using `alarm()` and `siglongjmp()`. When doing this, libcurl used a global buffer that was not mutex protected and a multi-threaded application might therefore crash or otherwise misbehave. Macos, Curl, Clustered_data_ontap, H300s_firmware, H410s_firmware, H500s_firmware, H700s_firmware, Ontap_antivirus_connector 5.9
2023-05-26 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... Macos, Debian_linux, Fedora, Curl, Clustered_data_ontap, H300s_firmware, H410s_firmware, H500s_firmware, H700s_firmware, Ontap_antivirus_connector 5.9
2023-05-26 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. 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 second transfer.... Macos, Fedora, Curl, Clustered_data_ontap, H300s_firmware, H410s_firmware, H500s_firmware, H700s_firmware, Ontap_antivirus_connector 3.7
2023-08-22 CVE-2020-19909 Integer overflow vulnerability in tool_operate.c in curl 7.65.2 via a large value as the retry delay. NOTE: many parties report that this has no direct security impact on the curl user; however, it may (in theory) cause a denial of service to associated systems or networks if, for example, --retry-delay is misinterpreted as a value much smaller than what was intended. This is not especially plausible because the overflow only happens if the user was trying to specify that curl should wait... Curl 3.3
2023-09-15 CVE-2023-38039 When curl retrieves an HTTP response, it stores the incoming headers so that they can be accessed later via the libcurl headers API. However, curl did not have a limit in how many or how large headers it would accept in a response, allowing a malicious server to stream an endless series of headers and eventually cause curl to run out of heap memory. Fedora, Curl, Windows_10_1809, Windows_10_21h2, Windows_10_22h2, Windows_11_21h2, Windows_11_22h2, Windows_11_23h2, Windows_server_2019, Windows_server_2022 7.5
2023-12-07 CVE-2023-46218 This flaw allows a malicious HTTP server to set "super cookies" in curl that are then passed back to more origins than what is otherwise allowed or possible. This allows a site to set cookies that then would get sent to different and unrelated sites and domains. It could do this by exploiting a mixed case flaw in curl's function that verifies a given cookie domain against the Public Suffix List (PSL). For example a cookie could be set with `domain=co.UK` when the URL used a lower case... Fedora, Curl 6.5
2023-12-12 CVE-2023-46219 When saving HSTS data to an excessively long file name, curl could end up removing all contents, making subsequent requests using that file unaware of the HSTS status they should otherwise use. Fedora, Curl 5.3
2024-02-03 CVE-2024-0853 curl inadvertently kept the SSL session ID for connections in its cache even when the verify status (*OCSP stapling*) test failed. A subsequent transfer to the same hostname could then succeed if the session ID cache was still fresh, which then skipped the verify status check. Curl 5.3
2018-03-12 CVE-2016-9952 The verify_certificate function in lib/vtls/schannel.c in libcurl 7.30.0 through 7.51.0, when built for Windows CE using the schannel TLS backend, makes it easier for remote attackers to conduct man-in-the-middle attacks via a crafted wildcard SAN in a server certificate, as demonstrated by "*.com." Curl 8.1
2016-05-20 CVE-2016-3739 The (1) mbed_connect_step1 function in lib/vtls/mbedtls.c and (2) polarssl_connect_step1 function in lib/vtls/polarssl.c in cURL and libcurl before 7.49.0, when using SSLv3 or making a TLS connection to a URL that uses a numerical IP address, allow remote attackers to spoof servers via an arbitrary valid certificate. Curl 5.3
