CVSS: 9.8EPSS: 6%CPEs: 42EXPL: 0CVE-2021-3711 – SM2 Decryption Buffer Overflow
https://notcve.org/view.php?id=CVE-2021-3711
In order to decrypt SM2 encrypted data an application is expected to call the API function EVP_PKEY_decrypt(). Typically an application will call this function twice. The first time, on entry, the "out" parameter can be NULL and, on exit, the "outlen" parameter is populated with the buffer size required to hold the decrypted plaintext. The application can then allocate a sufficiently sized buffer and call EVP_PKEY_decrypt() again, but this time passing a non-NULL value for the "out" parameter. A bug in the implementation of the SM2 decryption code means that the calculation of the buffer size required to hold the plaintext returned by the first call to EVP_PKEY_decrypt() can be smaller than the actual size required by the second call. • http://www.openwall.com/lists/oss-security/2021/08/26/2 https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf https://git.openssl.org/gitweb/?p=openssl.git%3Ba=commitdiff%3Bh=59f5e75f3bced8fc0e130d72a3f582cf7b480b46 https://lists.apache.org/thread.html/r18995de860f0e63635f3008fd2a6aca82394249476d21691e7c59c9e%40%3Cdev.tomcat.apache.org%3E https://lists.apache.org/thread.html/rad5d9f83f0d11fb3f8bb148d179b8a9ad7c6a17f18d70e5805a713d1%40%3Cdev.tomcat.apache.org%3E https://security.gentoo.org/glsa/202209-02 https://security.ge • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') CWE-787: Out-of-bounds Write •

Node.js before 16.6.0, 14.17.4, and 12.22.4 is vulnerable to Remote Code Execution, XSS, Application crashes due to missing input validation of host names returned by Domain Name Servers in Node.js dns library which can lead to output of wrong hostnames (leading to Domain Hijacking) and injection vulnerabilities in applications using the library. Node.js versiones anteriores a 16.6.0, 14.17.4 y 12.22.4, es vulnerable a una Ejecución de Código Remota , ataques de tipo XSS, bloqueo de Aplicaciones debido a una falta de comprobación de entrada de los nombres de host devueltos por los Servidores de Nombres de Dominio en la librería dns de Node.js, que puede conllevar a la salida de nombres de host erróneos (conllevando al Secuestro de Dominio) y vulnerabilidades de inyección en aplicaciones que usan la librería. A flaw was found in Node.js. These vulnerabilities include remote code execution, Cross-site scripting (XSS), application crashes due to missing input validation of hostnames returned by Domain Name Servers in the Node.js DNS library, which can lead to the output of wrong hostnames (leading to Domain hijacking) and injection vulnerabilities in applications using the library. • https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf https://hackerone.com/reports/1178337 https://nodejs.org/en/blog/vulnerability/aug-2021-security-releases https://security.gentoo.org/glsa/202401-02 https://security.netapp.com/advisory/ntap-20210923-0001 https://security.netapp.com/advisory/ntap-20211022-0003 https://www.oracle.com/security-alerts/cpujan2022.html https://www.oracle.com/security-alerts/cpujul2022.html https://www.oracle.com/security-alerts/cpuoct2021.html https:&# • CWE-20: Improper Input Validation CWE-170: Improper Null Termination •

https://notcve.org/view.php?id=CVE-2021-22926
libcurl-using applications can ask for a specific client certificate to be used in a transfer. This is done with the `CURLOPT_SSLCERT` option (`--cert` with the command line tool).When libcurl is built to use the macOS native TLS library Secure Transport, an application can ask for the client certificate by name or with a file name - using the same option. If the name exists as a file, it will be used instead of by name.If the appliction runs with a current working directory that is writable by other users (like `/tmp`), a malicious user can create a file name with the same name as the app wants to use by name, and thereby trick the application to use the file based cert instead of the one referred to by name making libcurl send the wrong client certificate in the TLS connection handshake. Las aplicaciones que usan libcurl pueden pedir un certificado de cliente específico para ser usado en una transferencia. Esto se hace con la opción "CURLOPT_SSLCERT" ("--cert" con la herramienta de línea de comandos).Cuando libcurl se construye para usar la biblioteca TLS nativa de macOS Transporte Seguro, una aplicación puede pedir el certificado del cliente por su nombre o con un nombre de archivo - usando la misma opción. • https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf https://hackerone.com/reports/1234760 https://lists.apache.org/thread.html/r61db8e7dcb56dc000a5387a88f7a473bacec5ee01b9ff3f55308aacc%40%3Cdev.kafka.apache.org%3E https://lists.apache.org/thread.html/r61db8e7dcb56dc000a5387a88f7a473bacec5ee01b9ff3f55308aacc%40%3Cusers.kafka.apache.org%3E https://lists.apache.org/thread.html/rbf4ce74b0d1fa9810dec50ba3ace0caeea677af7c27a97111c06ccb7%40%3Cdev.kafka.apache.org%3E https://lists.apache.org/thread.html/rbf4ce74b0d1fa9810dec50ba3ace0caeea677af7c27a97111c06ccb7%40%3Cuser • CWE-295: Improper Certificate Validation CWE-840: Business Logic Errors •
