2021-09-23 CVE-2021-22945 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*. Macos, Debian_linux, Fedora, Libcurl, Cloud_backup, Clustered_data_ontap, H300e_firmware, H300s_firmware, H410s_firmware, H500e_firmware, H500s_firmware, H700e_firmware, H700s_firmware, Solidfire_baseboard_management_controller_firmware, Mysql_server, Sinec_ins, Universal_forwarder 9.1
2023-03-30 CVE-2023-27535 An authentication bypass vulnerability exists in libcurl <8.0.0 in the FTP connection reuse feature that can result in wrong credentials being used during subsequent transfers. Previously created connections are kept in a connection pool for reuse if they match the current setup. However, certain FTP settings such as CURLOPT_FTP_ACCOUNT, CURLOPT_FTP_ALTERNATIVE_TO_USER, CURLOPT_FTP_SSL_CCC, and CURLOPT_USE_SSL were not included in the configuration match checks, causing them to match too... Debian_linux, Fedora, Libcurl, Active_iq_unified_manager, H300s_firmware, H410s_firmware, H500s_firmware, H700s_firmware, Ontap_9, Universal_forwarder 5.9
2023-03-30 CVE-2023-27538 An authentication bypass vulnerability exists in libcurl prior to v8.0.0 where it reuses a previously established SSH connection despite the fact that an SSH option was modified, which should have prevented reuse. libcurl maintains a pool of previously used connections to reuse them for subsequent transfers if the configurations match. However, two SSH settings were omitted from the configuration check, allowing them to match easily, potentially leading to the reuse of an inappropriate connection. Brocade_fabric_operating_system_firmware, Debian_linux, Fedora, Libcurl, Active_iq_unified_manager, Clustered_data_ontap, H300s_firmware, H410s_firmware, H500s_firmware, H700s_firmware, Universal_forwarder 5.5
2023-03-30 CVE-2023-27537 A double free vulnerability exists in libcurl <8.0.0 when sharing HSTS data between separate "handles". This sharing was introduced without considerations for do this sharing across separate threads but there was no indication of this fact in the documentation. Due to missing mutexes or thread locks, two threads sharing the same HSTS data could end up doing a double-free or use-after-free. Brocade_fabric_operating_system_firmware, Libcurl, Active_iq_unified_manager, Clustered_data_ontap, H300s_firmware, H410s_firmware, H500s_firmware, H700s_firmware, Universal_forwarder 5.9
2024-07-24 CVE-2024-6874 libcurl's URL API function [curl_url_get()](https://curl.se/libcurl/c/curl_url_get.html) offers punycode conversions, to and from IDN. Asking to convert a name that is exactly 256 bytes, libcurl ends up reading outside of a stack based buffer when built to use the *macidn* IDN backend. The conversion function then fills up the provided buffer exactly - but does not null terminate the string. This flaw can lead to stack contents accidently getting returned as part of the converted string. Libcurl 4.3
2024-07-31 CVE-2024-7264 libcurl's ASN1 parser code has the `GTime2str()` function, used for parsing an ASN.1 Generalized Time field. If given an syntactically incorrect field, the parser might end up using -1 for the length of the *time fraction*, leading to a `strlen()` getting performed on a pointer to a heap buffer area that is not (purposely) null terminated. This flaw most likely leads to a crash, but can also lead to heap contents getting returned to the application... Libcurl 6.5
2024-08-19 CVE-2024-32928 The libcurl CURLOPT_SSL_VERIFYPEER option was disabled on a subset of requests made by Nest production devices which enabled a potential man-in-the-middle attack on requests to Google cloud services by any host the traffic was routed through. Nest_mini_firmware, Libcurl 5.9
2005-05-02 CVE-2005-0490 Multiple stack-based buffer overflows in libcURL and cURL 7.12.1, and possibly other versions, allow remote malicious web servers to execute arbitrary code via base64 encoded replies that exceed the intended buffer lengths when decoded, which is not properly handled by (1) the Curl_input_ntlm function in http_ntlm.c during NTLM authentication or (2) the Curl_krb_kauth and krb4_auth functions in krb4.c during Kerberos authentication. Curl, Libcurl 8.8
2016-08-10 CVE-2016-5419 curl and libcurl before 7.50.1 do not prevent TLS session resumption when the client certificate has changed, which allows remote attackers to bypass intended restrictions by resuming a session. Debian_linux, Libcurl, Leap 7.5
2016-08-10 CVE-2016-5420 curl and libcurl before 7.50.1 do not check the client certificate when choosing the TLS connection to reuse, which might allow remote attackers to hijack the authentication of the connection by leveraging a previously created connection with a different client certificate. Debian_linux, Libcurl, Leap 7.5
