CVSS: 7.4EPSS: 0%CPEs: 56EXPL: 0CVE-2021-3450 – CA certificate check bypass with X509_V_FLAG_X509_STRICT
https://notcve.org/view.php?id=CVE-2021-3450
The X509_V_FLAG_X509_STRICT flag enables additional security checks of the certificates present in a certificate chain. It is not set by default. Starting from OpenSSL version 1.1.1h a check to disallow certificates in the chain that have explicitly encoded elliptic curve parameters was added as an additional strict check. An error in the implementation of this check meant that the result of a previous check to confirm that certificates in the chain are valid CA certificates was overwritten. This effectively bypasses the check that non-CA certificates must not be able to issue other certificates. • http://www.openwall.com/lists/oss-security/2021/03/27/1 http://www.openwall.com/lists/oss-security/2021/03/27/2 http://www.openwall.com/lists/oss-security/2021/03/28/3 http://www.openwall.com/lists/oss-security/2021/03/28/4 https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf https://git.openssl.org/gitweb/?p=openssl.git%3Ba=commitdiff%3Bh=2a40b7bc7b94dd7de897a74571e7024f0cf0d63b https://kb.pulsesecure.net/articles/Pulse_Security_Advisories/SA44845 https://kc.mc • CWE-295: Improper Certificate Validation •

Nessus Agent versions 7.2.0 through 8.2.2 were found to inadvertently capture the IAM role security token on the local host during initial linking of the Nessus Agent when installed on an Amazon EC2 instance. This could allow a privileged attacker to obtain the token. Se encontró que las versiones 7.2.0 a 8.2.2 del Agente Nessus capturan inadvertidamente el token de seguridad del rol IAM en el host local durante la vinculación inicial del Agente Nessus cuando se instala en una instancia de Amazon EC2.

A vulnerability in Nessus versions 8.9.0 through 8.12.0 for Windows & Nessus Agent 8.0.0 and 8.1.0 for Windows could allow an authenticated local attacker to copy user-supplied files to a specially constructed path in a specifically named user directory. An attacker could exploit this vulnerability by creating a malicious file and copying the file to a system directory. The attacker needs valid credentials on the Windows system to exploit this vulnerability. Una vulnerabilidad en Nessus versiones 8.9.0 a 8.12.0, para Windows y Nessus Agent versiones 8.0.0 y 8.1.0 para Windows, podría permitir a un atacante local autenticado copiar archivos suministrados por el usuario en una ruta especialmente construida en un directorio de usuario con nombre específico. Un atacante podría explotar esta vulnerabilidad mediante la creación de un archivo malicioso y copiar el archivo en un directorio del sistema. • https://www.tenable.com/security/tns-2020-07 https://www.tenable.com/security/tns-2020-08 •

https://notcve.org/view.php?id=CVE-2019-16168
In SQLite through 3.29.0, whereLoopAddBtreeIndex in sqlite3.c can crash a browser or other application because of missing validation of a sqlite_stat1 sz field, aka a "severe division by zero in the query planner." En SQLite versiones hasta 3.29.0, la función whereLoopAddBtreeIndex en el archivo sqlite3.c puede bloquear un navegador u otra aplicación debido a la falta de comprobación de un campo sqlite_stat1 sz, también se conoce como "severe division by zero in the query planner.". • http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00032.html http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00033.html https://kc.mcafee.com/corporate/index?page=content&id=SB10365 https://lists.debian.org/debian-lts-announce/2020/08/msg00037.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/XZARJHJJDBHI7CE5PZEBXS5HKK6HXKW2 https://security.gentoo.org/glsa/202003-16 https://security.netapp.com/advisory/ntap-20190926-0003 https:/& • CWE-369: Divide By Zero •
CVSS: 5.9EPSS: 1%CPEs: 180EXPL: 0CVE-2019-1559 – 0-byte record padding oracle
https://notcve.org/view.php?id=CVE-2019-1559
If an application encounters a fatal protocol error and then calls SSL_shutdown() twice (once to send a close_notify, and once to receive one) then OpenSSL can respond differently to the calling application if a 0 byte record is received with invalid padding compared to if a 0 byte record is received with an invalid MAC. If the application then behaves differently based on that in a way that is detectable to the remote peer, then this amounts to a padding oracle that could be used to decrypt data. In order for this to be exploitable "non-stitched" ciphersuites must be in use. Stitched ciphersuites are optimised implementations of certain commonly used ciphersuites. Also the application must call SSL_shutdown() twice even if a protocol error has occurred (applications should not do this but some do anyway). • http://lists.opensuse.org/opensuse-security-announce/2019-03/msg00041.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00019.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00046.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00047.html http://lists.opensuse.org/opensuse-security-announce/2019-05/msg00049.html http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00080.html http://www.securityfocus.com/bid/107174 https://access. • CWE-203: Observable Discrepancy CWE-325: Missing Cryptographic Step •
