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 •

A segmentation fault can occur in the sqlite3.exe command-line component of SQLite 3.36.0 via the idxGetTableInfo function when there is a crafted SQL query. NOTE: the vendor disputes the relevance of this report because a sqlite3.exe user already has full privileges (e.g., is intentionally allowed to execute commands). This report does NOT imply any problem in the SQLite library. ** EN DISPUTA ** Puede producirse un fallo de segmentación en el componente command-line sqlite3.exe de SQLite versión 3.36.0 por medio de la función idxGetTableInfo cuando hay una consulta SQL manipulada. NOTA: el proveedor disputa la relevancia de este informe porque un usuario de sqlite3.exe ya tiene privilegios completos (por ejemplo, se le permite intencionadamente ejecutar comandos). Este informe NO implica ningún problema en la biblioteca SQLite. • http://seclists.org/fulldisclosure/2022/Oct/28 http://seclists.org/fulldisclosure/2022/Oct/39 http://seclists.org/fulldisclosure/2022/Oct/41 http://seclists.org/fulldisclosure/2022/Oct/47 http://seclists.org/fulldisclosure/2022/Oct/49 https://support.apple.com/kb/HT213446 https://support.apple.com/kb/HT213486 https://support.apple.com/kb/HT213487 https://support.apple.com/kb/HT213488 https://www.sqlite.org/forum/forumpost/718c0a8d17 •

A crafted method sent through HTTP/2 will bypass validation and be forwarded by mod_proxy, which can lead to request splitting or cache poisoning. This issue affects Apache HTTP Server 2.4.17 to 2.4.48. Un método diseñado enviado mediante HTTP/2 omitirá la comprobación y será reenviado por mod_proxy, lo que puede conllevar a la división de peticiones o el envenenamiento de la caché. Este problema afecta a Apache HTTP Server versiones 2.4.17 a 2.4.48. A NULL pointer dereference was found in Apache httpd mod_h2. • https://github.com/apache/httpd/commit/ecebcc035ccd8d0e2984fe41420d9e944f456b3c.patch https://lists.apache.org/thread.html/re4162adc051c1a0a79e7a24093f3776373e8733abaff57253fef341d%40%3Ccvs.httpd.apache.org%3E https://lists.apache.org/thread.html/ree7519d71415ecdd170ff1889cab552d71758d2ba2904a17ded21a70%40%3Ccvs.httpd.apache.org%3E https://lists.debian.org/debian-lts-announce/2023/03/msg00002.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/DSM6UWQICBJ2TU727RENU3HBKEAFLT6T https://lists.fedoraproject.org/archives&#x • CWE-476: NULL Pointer Dereference •
