Node.js versions before 10.23.1, 12.20.1, 14.15.4, 15.5.1 allow two copies of a header field in an HTTP request (for example, two Transfer-Encoding header fields). In this case, Node.js identifies the first header field and ignores the second. This can lead to HTTP Request Smuggling. Node.js versiones anteriores a 10.23.1, 12.20.1, 14.15.4, 15.5.1 permiten dos copias de un campo de encabezado en una petición HTTP (por ejemplo, dos campos de encabezado Transfer-Encoding). En este caso, Node.js identifica el primer campo de encabezado e ignora el segundo. • https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf https://hackerone.com/reports/1002188 https://lists.debian.org/debian-lts-announce/2022/12/msg00009.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/H472D5HPXN6RRXCNFML3BK5OYC52CXF2 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/K4I6MZNC7C7VIDQR267OL4TVCI3ZKAC4 https://nodejs.org/en/blog/vulnerability/january-2021-security-releases https://security.gentoo.org/glsa/2021 • CWE-444: Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') •

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 potencialmente hacer que curl extraiga información sobre servicios que de otro modo serían privados y no divulgados, por ejemplo, haciendo escaneo de puerto y extracciones del banner de servicio A malicious server can use the `PASV` response to trick curl 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. If curl operates on a URL provided by a user, a user can exploit that and pass in a URL to a malicious FTP server instance without needing any server breach to perform the attack. • https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf https://curl.se/docs/CVE-2020-8284.html https://hackerone.com/reports/1040166 https://lists.debian.org/debian-lts-announce/2020/12/msg00029.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/DAEHE2S2QLO4AO4MEEYL75NB7SAH5PSL https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/NZUVSQHN2ESHMJXNQ2Z7T2EELBB5HJXG https://security.gentoo.org/glsa/202012-14 https://securi • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

curl 7.21.0 to and including 7.73.0 is vulnerable to uncontrolled recursion due to a stack overflow issue in FTP wildcard match parsing. curl versiones 7.21.0 hasta 7.73.0 e incluyéndola, es vulnerable a una recursividad no controlada debido a un problema de desbordamiento de la pila en el análisis de coincidencias del comodín FTP Libcurl offers a wildcard matching functionality, which allows a callback (set with `CURLOPT_CHUNK_BGN_FUNCTION`) to return information back to libcurl on how to handle a specific entry in a directory when libcurl iterates over a list of all available entries. When this callback returns `CURL_CHUNK_BGN_FUNC_SKIP`, to tell libcurl to not deal with that file, the internal function in libcurl then calls itself recursively to handle the next directory entry. If there's a sufficient amount of file entries and if the callback returns "skip" enough number of times, libcurl runs out of stack space. The exact amount will of course vary with platforms, compilers and other environmental factors. • http://seclists.org/fulldisclosure/2021/Apr/51 https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf https://curl.se/docs/CVE-2020-8285.html https://github.com/curl/curl/issues/6255 https://hackerone.com/reports/1045844 https://lists.apache.org/thread.html/r58af02e294bd07f487e2c64ffc0a29b837db5600e33b6e698b9d696b%40%3Cissues.bookkeeper.apache.org%3E https://lists.apache.org/thread.html/rf4c02775860db415b4955778a131c2795223f61cb8c6a450893651e4%40%3Cissues.bookkeeper.apache.org%3E https://lists.debian.org/debian-lts • CWE-121: Stack-based Buffer Overflow CWE-674: Uncontrolled Recursion CWE-787: Out-of-bounds Write •

curl 7.41.0 through 7.73.0 is vulnerable to an improper check for certificate revocation due to insufficient verification of the OCSP response. curl versiones 7.41.0 hasta 7.73.0, es vulnerable a una comprobación inapropiada para la revocación del certificado debido a una verificación insuficiente de la respuesta OCSP Libcurl offers "OCSP stapling" via the CURLOPT_SSL_VERIFYSTATUS option. When set, libcurl verifies the OCSP response that a server responds with as part of the TLS handshake. It then aborts the TLS negotiation if something is wrong with the response. The same feature can be enabled with --cert-status using the curl tool. As part of the OCSP response verification, a client should verify that the response is indeed set out for the correct certificate. • http://seclists.org/fulldisclosure/2021/Apr/50 http://seclists.org/fulldisclosure/2021/Apr/51 http://seclists.org/fulldisclosure/2021/Apr/54 https://cert-portal.siemens.com/productcert/pdf/ssa-200951.pdf https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf https://curl.se/docs/CVE-2020-8286.html https://hackerone.com/reports/1048457 https://lists.debian.org/debian-lts-announce/2020/12/msg00029.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fe • CWE-295: Improper Certificate Validation •

The X.509 GeneralName type is a generic type for representing different types of names. One of those name types is known as EDIPartyName. OpenSSL provides a function GENERAL_NAME_cmp which compares different instances of a GENERAL_NAME to see if they are equal or not. This function behaves incorrectly when both GENERAL_NAMEs contain an EDIPARTYNAME. A NULL pointer dereference and a crash may occur leading to a possible denial of service attack. • https://github.com/MBHudson/CVE-2020-1971 http://www.openwall.com/lists/oss-security/2021/09/14/2 https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf https://git.openssl.org/gitweb/?p=openssl.git%3Ba=commitdiff%3Bh=2154ab83e14ede338d2ede9bbe5cdfce5d5a6c9e https://git.openssl.org/gitweb/?p=openssl.git%3Ba=commitdiff%3Bh=f960d81215ebf3f65e03d4d5d857fb9b666d6920 https://kb.pulsesecure.net/articles/Pulse_Security_Advisories/SA44676 https://lists.apache.org/thread.html/r63c6f2dd363d9b514d0a4bcf624580616a679898cc14c109a49b7 • CWE-476: NULL Pointer Dereference •
