| CVE-2024-7264 | 1 Haxx | 1 Libcurl | 2024-10-30 | N/A | 6.5 MEDIUM |
| 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 when [CURLINFO_CERTINFO](https://curl.se/libcurl/c/CURLINFO_CERTINFO.html) is used. | |||||
| CVE-2022-43552 | 3 Apple, Haxx, Splunk | 3 Macos, Curl, Universal Forwarder | 2024-10-27 | N/A | 5.9 MEDIUM |
| A use after free vulnerability exists in curl <7.87.0. Curl can be asked to *tunnel* virtually all protocols it supports through an HTTP proxy. HTTP proxies can (and often do) deny such tunnel operations. When getting denied to tunnel the specific protocols SMB or TELNET, curl would use a heap-allocated struct after it had been freed, in its transfer shutdown code path. | |||||
| CVE-2023-38545 | 4 Fedoraproject, Haxx, Microsoft and 1 more | 13 Fedora, Libcurl, Windows 10 1809 and 10 more | 2024-10-17 | N/A | 9.8 CRITICAL |
| This flaw makes curl overflow a heap based buffer in the SOCKS5 proxy handshake. When curl is asked to pass along the host name to the SOCKS5 proxy to allow that to resolve the address instead of it getting done by curl itself, the maximum length that host name can be is 255 bytes. If the host name is detected to be longer, curl switches to local name resolving and instead passes on the resolved address only. Due to this bug, the local variable that means "let the host resolve the name" could get the wrong value during a slow SOCKS5 handshake, and contrary to the intention, copy the too long host name to the target buffer instead of copying just the resolved address there. The target buffer being a heap based buffer, and the host name coming from the URL that curl has been told to operate with. | |||||
| CVE-2024-6874 | 1 Haxx | 1 Libcurl | 2024-09-10 | N/A | 4.3 MEDIUM |
| 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. | |||||
| CVE-2024-6197 | 1 Haxx | 1 Libcurl | 2024-08-26 | N/A | 7.5 HIGH |
| libcurl's ASN1 parser has this utf8asn1str() function used for parsing an ASN.1 UTF-8 string. Itcan detect an invalid field and return error. Unfortunately, when doing so it also invokes `free()` on a 4 byte localstack buffer. Most modern malloc implementations detect this error and immediately abort. Some however accept the input pointer and add that memory to its list of available chunks. This leads to the overwriting of nearby stack memory. The content of the overwrite is decided by the `free()` implementation; likely to be memory pointers and a set of flags. The most likely outcome of exploting this flaw is a crash, although it cannot be ruled out that more serious results can be had in special circumstances. | |||||
| CVE-2024-32928 | 2 Google, Haxx | 3 Nest Mini, Nest Mini Firmware, Libcurl | 2024-08-20 | N/A | 5.9 MEDIUM |
| 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. | |||||
| CVE-2022-27780 | 3 Haxx, Netapp, Splunk | 15 Curl, Clustered Data Ontap, H300s and 12 more | 2024-08-07 | 5.0 MEDIUM | 7.5 HIGH |
| The curl URL parser wrongly accepts percent-encoded URL separators like '/'when decoding the host name part of a URL, making it a *different* URL usingthe wrong host name when it is later retrieved.For example, a URL like `http://example.com%2F127.0.0.1/`, would be allowed bythe parser and get transposed into `http://example.com/127.0.0.1/`. This flawcan be used to circumvent filters, checks and more. | |||||
| CVE-2020-19909 | 1 Haxx | 1 Curl | 2024-08-04 | N/A | 3.3 LOW |
| 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 weeks (or longer) before trying to recover from a transient error. | |||||
| CVE-2016-9952 | 2 Haxx, Microsoft | 2 Curl, Windows Embedded Compact | 2024-08-01 | 6.8 MEDIUM | 8.1 HIGH |
| 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." | |||||
| CVE-2023-38546 | 1 Haxx | 1 Libcurl | 2024-07-09 | N/A | 3.7 LOW |
| This flaw allows an attacker to insert cookies at will into a running program using libcurl, if the specific series of conditions are met. libcurl performs transfers. In its API, an application creates "easy handles" that are the individual handles for single transfers. libcurl provides a function call that duplicates en easy handle called [curl_easy_duphandle](https://curl.se/libcurl/c/curl_easy_duphandle.html). If a transfer has cookies enabled when the handle is duplicated, the cookie-enable state is also cloned - but without cloning the actual cookies. If the source handle did not read any cookies from a specific file on disk, the cloned version of the handle would instead store the file name as `none` (using the four ASCII letters, no quotes). Subsequent use of the cloned handle that does not explicitly set a source to load cookies from would then inadvertently load cookies from a file named `none` - if such a file exists and is readable in the current directory of the program using libcurl. And if using the correct file format of course. | |||||
| CVE-2024-0853 | 1 Haxx | 1 Curl | 2024-05-03 | N/A | 5.3 MEDIUM |
| 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. | |||||
| CVE-2016-3739 | 1 Haxx | 1 Curl | 2024-05-01 | 2.6 LOW | 5.3 MEDIUM |
| 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. | |||||
| CVE-2020-8284 | 9 Apple, Debian, Fedoraproject and 6 more | 29 Mac Os X, Macos, Debian Linux and 26 more | 2024-04-08 | 4.3 MEDIUM | 3.7 LOW |
| A malicious server can use the FTP PASV response to trick curl 7.73.0 and earlier into connecting back to a given IP address and port, and this way potentially make curl extract information about services that are otherwise private and not disclosed, for example doing port scanning and service banner extractions. | |||||
| CVE-2023-38039 | 3 Fedoraproject, Haxx, Microsoft | 10 Fedora, Curl, Windows 10 1809 and 7 more | 2024-04-01 | N/A | 7.5 HIGH |
| 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. | |||||

| curl 7.1.1 to and including 7.75.0 is vulnerable to an "Exposure of Private Personal Information to an Unauthorized Actor" by leaking credentials in the HTTP Referer: header. libcurl does not strip off user credentials from the URL when automatically populating the Referer: HTTP request header field in outgoing HTTP requests, and therefore risks leaking sensitive data to the server that is the target of the second HTTP request. | |||||
