CVE-2022-27782 – curl: TLS and SSH connection too eager reuse
https://notcve.org/view.php?id=CVE-2022-27782
11 May 2022 — libcurl would reuse a previously created connection even when a TLS or SSHrelated option had been changed that should have prohibited reuse.libcurl keeps previously used connections in a connection pool for subsequenttransfers to reuse if one of them matches the setup. However, several TLS andSSH settings were left out from the configuration match checks, making themmatch too easily. libcurl reusaba una conexión creada previamente incluso cuando había sido cambiada una opción relacionada con TLS o SSH que d... • http://www.openwall.com/lists/oss-security/2023/03/20/6 • CWE-295: Improper Certificate Validation CWE-840: Business Logic Errors •

CVE-2020-8284 – curl: FTP PASV command response can cause curl to connect to arbitrary host
https://notcve.org/view.php?id=CVE-2020-8284
09 Dec 2020 — 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. Un servidor malicioso puede usar la respuesta FTP PASV para engañar a curl versiones 7.73.0 y anteriores, para que se conecte de nuevo a una dirección IP y puerto determinados, y de esta manera pot... • https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

02 Jul 2019 — A non-privileged user or program can put code and a config file in a known non-privileged path (under C:/usr/local/) that will make curl <= 7.65.1 automatically run the code (as an openssl "engine") on invocation. If that curl is invoked by a privileged user it can do anything it wants.

CVE-2017-9502
https://notcve.org/view.php?id=CVE-2017-9502
14 Jun 2017 — In curl before 7.54.1 on Windows and DOS, libcurl's default protocol function, which is the logic that allows an application to set which protocol libcurl should attempt to use when given a URL without a scheme part, had a flaw that could lead to it overwriting a heap based memory buffer with seven bytes. If the default protocol is specified to be FILE or a file: URL lacks two slashes, the given "URL" starts with a drive letter, and libcurl is built for Windows or DOS, then libcurl would copy the path 7 byt... • http://openwall.com/lists/oss-security/2017/06/14/1 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

CVE-2017-2629 – Apple Security Advisory 2017-07-19-2
https://notcve.org/view.php?id=CVE-2017-2629
28 Mar 2017 — curl before 7.53.0 has an incorrect TLS Certificate Status Request extension feature that asks for a fresh proof of the server's certificate's validity in the code that checks for a test success or failure. It ends up always thinking there's valid proof, even when there is none or if the server doesn't support the TLS extension in question. This could lead to users not detecting when a server's certificate goes invalid or otherwise be mislead that the server is in a better shape than it is in reality.
