| 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 |
| 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 |
| 2019-02-06 | 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 |
| 2018-09-05 | 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 |
| 2018-07-31 | CVE-2016-8622 | Out-of-bounds Write vulnerability in Haxx Libcurl The URL percent-encoding decode function in libcurl before 7.51.0 is called `curl_easy_unescape`. | 9.8 |
| 2016-10-07 | CVE-2016-7167 | Integer Overflow or Wraparound vulnerability in multiple products Multiple integer overflows in the (1) curl_escape, (2) curl_easy_escape, (3) curl_unescape, and (4) curl_easy_unescape functions in libcurl before 7.50.3 allow attackers to have unspecified impact via a string of length 0xffffffff, which triggers a heap-based buffer overflow. | 9.8 |
| 2015-04-24 | CVE-2015-3144 | Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in multiple products The fix_hostname function in cURL and libcurl 7.37.0 through 7.41.0 does not properly calculate an index, which allows remote attackers to cause a denial of service (out-of-bounds read or write and crash) or possibly have other unspecified impact via a zero-length host name, as demonstrated by "http://:80" and ":80." The previous CVSS assessment 7.5 (AV:N/AC:L/AU:N/C:P/I:P/A:P) was provided at the time of initial analysis based on the best available published information at that time. | 9.0 |
