https://notcve.org/view.php?id=CVE-2023-4459
A NULL pointer dereference flaw was found in vmxnet3_rq_cleanup in drivers/net/vmxnet3/vmxnet3_drv.c in the networking sub-component in vmxnet3 in the Linux Kernel. This issue may allow a local attacker with normal user privilege to cause a denial of service due to a missing sanity check during cleanup. • https://access.redhat.com/errata/RHSA-2024:0412 https://access.redhat.com/errata/RHSA-2024:1250 https://access.redhat.com/errata/RHSA-2024:1306 https://access.redhat.com/errata/RHSA-2024:1367 https://access.redhat.com/errata/RHSA-2024:1382 https://access.redhat.com/errata/RHSA-2024:2006 https://access.redhat.com/errata/RHSA-2024:2008 https://access.redhat.com/security/cve/CVE-2023-4459 https://bugzilla.redhat.com/show_bug.cgi?id=2219268 https://github.com/torvalds/ • CWE-476: NULL Pointer Dereference •

https://notcve.org/view.php?id=CVE-2023-4456
A flaw was found in openshift-logging LokiStack. The key used for caching is just the token, which is too broad. This issue allows a user with a token valid for one action to execute other actions as long as the authorization allowing the original action is still cached. Se encontró una falla en Openshift-logging LokiStack. La clave utilizada para el almacenamiento en caché es solo el token, que es demasiado amplio. • https://access.redhat.com/errata/RHSA-2023:4933 https://access.redhat.com/errata/RHSA-2023:5095 https://access.redhat.com/errata/RHSA-2023:5096 https://access.redhat.com/security/cve/CVE-2023-4456 https://bugzilla.redhat.com/show_bug.cgi?id=2233087 • CWE-1220: Insufficient Granularity of Access Control •

https://notcve.org/view.php?id=CVE-2023-4387
A use-after-free flaw was found in vmxnet3_rq_alloc_rx_buf in drivers/net/vmxnet3/vmxnet3_drv.c in VMware's vmxnet3 ethernet NIC driver in the Linux Kernel. This issue could allow a local attacker to crash the system due to a double-free while cleaning up vmxnet3_rq_cleanup_all, which could also lead to a kernel information leak problem. Se encontró una falla de use-after-free en vmxnet3_rq_alloc_rx_buf en drivers/net/vmxnet3/vmxnet3_drv.c en el controlador NIC Ethernet vmxnet3 de VMware en el kernel de Linux. Este problema podría permitir que un atacante local bloquee el sistema debido a una doble liberación mientras se limpia vmxnet3_rq_cleanup_all, lo que también podría provocar un problema de fuga de información del kernel. • https://access.redhat.com/security/cve/CVE-2023-4387 https://bugzilla.redhat.com/show_bug.cgi?id=2219270 https://github.com/torvalds/linux/commit/9e7fef9521e73ca8afd7da9e58c14654b02dfad8 • CWE-416: Use After Free •

https://notcve.org/view.php?id=CVE-2023-39418
A vulnerability was found in PostgreSQL with the use of the MERGE command, which fails to test new rows against row security policies defined for UPDATE and SELECT. If UPDATE and SELECT policies forbid some rows that INSERT policies do not forbid, a user could store such rows. Se encontró una vulnerabilidad en PostgreSQL con el uso del comando MERGE, que no puede probar nuevas filas con las políticas de seguridad de filas definidas para ACTUALIZAR y SELECCIONAR. Si las políticas ACTUALIZAR y SELECCIONAR prohíben algunas filas que las políticas INSERTAR no prohíben, un usuario podría almacenar dichas filas. • https://access.redhat.com/errata/RHSA-2023:7785 https://access.redhat.com/errata/RHSA-2023:7883 https://access.redhat.com/errata/RHSA-2023:7884 https://access.redhat.com/errata/RHSA-2023:7885 https://access.redhat.com/security/cve/CVE-2023-39418 https://bugzilla.redhat.com/show_bug.cgi?id=2228112 https://git.postgresql.org/gitweb/?p=postgresql.git;a=commitdiff;h=cb2ae5741f2458a474ed3c31458d242e678ff229 https://security.netapp.com/advisory/ntap-20230915-0002 https://www.debian.org/security •

https://notcve.org/view.php?id=CVE-2023-39417
IN THE EXTENSION SCRIPT, a SQL Injection vulnerability was found in PostgreSQL if it uses @extowner@, @extschema@, or @extschema:...@ inside a quoting construct (dollar quoting, '', or ""). If an administrator has installed files of a vulnerable, trusted, non-bundled extension, an attacker with database-level CREATE privilege can execute arbitrary code as the bootstrap superuser. EN EL SCRIPT DE EXTENSIÓN, se encontró una vulnerabilidad de inyección SQL en PostgreSQL si usa @extowner@, @extschema@ o @extschema:...@ dentro de una construcción de cotización (cotización en dólares, '' o ""). Si un administrador ha instalado archivos de una extensión vulnerable, de confianza y no empaquetada, un atacante con privilegios CREATE de nivel de base de datos puede ejecutar código arbitrario como superusuario de arranque. • https://access.redhat.com/errata/RHSA-2023:7545 https://access.redhat.com/errata/RHSA-2023:7579 https://access.redhat.com/errata/RHSA-2023:7580 https://access.redhat.com/errata/RHSA-2023:7581 https://access.redhat.com/errata/RHSA-2023:7616 https://access.redhat.com/errata/RHSA-2023:7656 https://access.redhat.com/errata/RHSA-2023:7666 https://access.redhat.com/errata/RHSA-2023:7667 https://access.redhat.com/errata/RHSA-2023:7694 https://access.redhat.com/errata/RHSA • CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') •
