CVSS: 7.5EPSS: 0%CPEs: 67EXPL: 1CVE-2021-23840 – Integer overflow in CipherUpdate
https://notcve.org/view.php?id=CVE-2021-23840
16 Feb 2021 — Calls to EVP_CipherUpdate, EVP_EncryptUpdate and EVP_DecryptUpdate may overflow the output length argument in some cases where the input length is close to the maximum permissable length for an integer on the platform. In such cases the return value from the function call will be 1 (indicating success), but the output length value will be negative. This could cause applications to behave incorrectly or crash. OpenSSL versions 1.1.1i and below are affected by this issue. Users of these versions should upgrad... • https://github.com/Trinadh465/openssl-1.1.1g_CVE-2021-23840 • CWE-190: Integer Overflow or Wraparound •
CVSS: 8.1EPSS: 0%CPEs: 10EXPL: 1CVE-2020-8265 – nodejs: use-after-free in the TLS implementation
https://notcve.org/view.php?id=CVE-2020-8265
06 Jan 2021 — Node.js versions before 10.23.1, 12.20.1, 14.15.4, 15.5.1 are vulnerable to a use-after-free bug in its TLS implementation. When writing to a TLS enabled socket, node::StreamBase::Write calls node::TLSWrap::DoWrite with a freshly allocated WriteWrap object as first argument. If the DoWrite method does not return an error, this object is passed back to the caller as part of a StreamWriteResult structure. This may be exploited to corrupt memory leading to a Denial of Service or potentially other exploits.

CVSS: 6.5EPSS: 9%CPEs: 10EXPL: 2CVE-2020-8287 – nodejs: HTTP request smuggling via two copies of a header field in an http request
https://notcve.org/view.php?id=CVE-2020-8287
06 Jan 2021 — 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 identific... • https://github.com/progfay/nodejs-http-transfer-encoding-smuggling-poc • CWE-444: Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') •
CVSS: 5.9EPSS: 0%CPEs: 75EXPL: 1CVE-2020-1971 – EDIPARTYNAME NULL pointer dereference
https://notcve.org/view.php?id=CVE-2020-1971
08 Dec 2020 — 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 • CWE-476: NULL Pointer Dereference •

https://notcve.org/view.php?id=CVE-2020-8277
19 Nov 2020 — A Node.js application that allows an attacker to trigger a DNS request for a host of their choice could trigger a Denial of Service in versions < 15.2.1, < 14.15.1, and < 12.19.1 by getting the application to resolve a DNS record with a larger number of responses. This is fixed in 15.2.1, 14.15.1, and 12.19.1. Una aplicación Node.js que permite a un atacante desencadenar una petición DNS para un host de su elección podría desencadenar una Denegación de servicio en las versiones anteriores a 15.2.1, versione... • https://github.com/masahiro331/CVE-2020-8277 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-400: Uncontrolled Resource Consumption •
