https://notcve.org/view.php?id=CVE-2021-23214
When the server is configured to use trust authentication with a clientcert requirement or to use cert authentication, a man-in-the-middle attacker can inject arbitrary SQL queries when a connection is first established, despite the use of SSL certificate verification and encryption. Cuando el servidor está configurado para usar la autenticación confiable con un requisito de clientcert o para usar la autenticación de cert, un atacante de tipo man-in-the-middle puede inyectar consultas SQL arbitrarias cuando es establecida una conexión por primera vez, a pesar del uso de la verificación y el cifrado del certificado SSL It was found that a PostgreSQL server could accept plain text data during the establishment of an SSL connection. When a user is requesting a certificate based authentication, an active Person in the Middle could use this flaw in order to inject arbitrary SQL commands. • https://bugzilla.redhat.com/show_bug.cgi?id=2022666 https://git.postgresql.org/gitweb/?p=postgresql.git%3Ba=commit%3Bh=28e24125541545483093819efae9bca603441951 https://github.com/postgres/postgres/commit/28e24125541545483093819efae9bca603441951 https://security.gentoo.org/glsa/202211-04 https://www.postgresql.org/support/security/CVE-2021-23214 https://access.redhat.com/security/cve/CVE-2021-23214 • CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') •

https://notcve.org/view.php?id=CVE-2021-32672
Redis is an open source, in-memory database that persists on disk. When using the Redis Lua Debugger, users can send malformed requests that cause the debugger’s protocol parser to read data beyond the actual buffer. This issue affects all versions of Redis with Lua debugging support (3.2 or newer). The problem is fixed in versions 6.2.6, 6.0.16 and 5.0.14. Redis es una base de datos en memoria de código abierto que persiste en el disco. • https://github.com/redis/redis/commit/6ac3c0b7abd35f37201ed2d6298ecef4ea1ae1dd https://github.com/redis/redis/security/advisories/GHSA-9mj9-xx53-qmxm https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/HTYQ5ZF37HNGTZWVNJD3VXP7I6MEEF42 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/VL5KXFN3ATM7IIM7Q4O4PWTSRGZ5744Z https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/WR5WKJWXD4D6S3DJCZ56V74ESLTDQRAB https://security.gentoo.org/gls • CWE-125: Out-of-bounds Read •
CVSS: 8.8EPSS: 0%CPEs: 76EXPL: 1CVE-2021-3656 – kernel: SVM nested virtualization issue in KVM (VMLOAD/VMSAVE)
https://notcve.org/view.php?id=CVE-2021-3656
A flaw was found in the KVM's AMD code for supporting SVM nested virtualization. The flaw occurs when processing the VMCB (virtual machine control block) provided by the L1 guest to spawn/handle a nested guest (L2). Due to improper validation of the "virt_ext" field, this issue could allow a malicious L1 to disable both VMLOAD/VMSAVE intercepts and VLS (Virtual VMLOAD/VMSAVE) for the L2 guest. As a result, the L2 guest would be allowed to read/write physical pages of the host, resulting in a crash of the entire system, leak of sensitive data or potential guest-to-host escape. Se ha encontrado un fallo en el código AMD de KVM para soportar la virtualización anidada SVM. • https://github.com/rami08448/CVE-2021-3656-Demo https://bugzilla.redhat.com/show_bug.cgi?id=1983988 https://git.kernel.org/pub/scm/virt/kvm/kvm.git/commit/?id=c7dfa4009965a9b2d7b329ee970eb8da0d32f0bc https://github.com/torvalds/linux/commit/c7dfa4009965a9b2d7b329ee970eb8da0d32f0bc https://www.openwall.com/lists/oss-security/2021/08/16/1 https://access.redhat.com/security/cve/CVE-2021-3656 • CWE-862: Missing Authorization •

https://notcve.org/view.php?id=CVE-2021-3677
A flaw was found in postgresql. A purpose-crafted query can read arbitrary bytes of server memory. In the default configuration, any authenticated database user can complete this attack at will. The attack does not require the ability to create objects. If server settings include max_worker_processes=0, the known versions of this attack are infeasible. • https://bugzilla.redhat.com/show_bug.cgi?id=2001857 https://security.gentoo.org/glsa/202211-04 https://security.netapp.com/advisory/ntap-20220407-0008 https://www.postgresql.org/support/security/CVE-2021-3677 https://access.redhat.com/security/cve/CVE-2021-3677 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

A flaw was found in postgresql in versions before 13.3, before 12.7, before 11.12, before 10.17 and before 9.6.22. While modifying certain SQL array values, missing bounds checks let authenticated database users write arbitrary bytes to a wide area of server memory. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. Se ha encontrado un fallo en postgresql en las versiones anteriores a 13.3, versiones anteriores a 12.7, versiones anteriores a 11.12, versiones anteriores a 10.17 y versiones anteriores a 9.6.22. Cuando se modifican determinados valores de matrices SQL, una falta de comprobación de límites permite a usuarios autentificados de la base de datos escribir bytes arbitrarios en una amplia zona de la memoria del servidor. • https://bugzilla.redhat.com/show_bug.cgi?id=1956876 https://security.gentoo.org/glsa/202211-04 https://security.netapp.com/advisory/ntap-20210713-0004 https://www.postgresql.org/support/security/CVE-2021-32027 https://access.redhat.com/security/cve/CVE-2021-32027 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-190: Integer Overflow or Wraparound •
