| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2023-10-18 | CVE-2023-38545 | Out-of-bounds Write vulnerability in multiple products 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. | 9.8 |
| 2023-02-23 | CVE-2023-23914 | Cleartext Transmission of Sensitive Information vulnerability in multiple products 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. | 9.1 |
| 2022-12-05 | CVE-2022-32221 | Exposure of Resource to Wrong Sphere vulnerability in multiple products 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. | 9.8 |
| 2022-07-07 | CVE-2022-32207 | Incorrect Default Permissions vulnerability in multiple products 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. | 9.8 |
| 2021-09-23 | CVE-2021-22945 | Double Free vulnerability in multiple products 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*. | 9.1 |
| 2019-09-16 | CVE-2019-5482 | Out-of-bounds Write vulnerability in multiple products Heap buffer overflow in the TFTP protocol handler in cURL 7.19.4 to 7.65.3. | 9.8 |
| 2019-09-16 | CVE-2019-5481 | Double Free vulnerability in multiple products Double-free vulnerability in the FTP-kerberos code in cURL 7.52.0 to 7.65.3. | 9.8 |
| 2019-02-06 | CVE-2019-3822 | Out-of-bounds Write vulnerability in multiple products libcurl versions from 7.36.0 to before 7.64.0 are vulnerable to a stack-based buffer overflow. | 9.8 |
| 2018-10-31 | CVE-2018-16839 | Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in multiple products Curl versions 7.33.0 through 7.61.1 are vulnerable to a buffer overrun in the SASL authentication code that may lead to denial of service. | 9.8 |
| 2018-09-05 | CVE-2018-14618 | Integer Overflow or Wraparound vulnerability in multiple products curl before version 7.61.1 is vulnerable to a buffer overrun in the NTLM authentication code. | 10.0 |
