CVE-2023-4387 – Kernel: vmxnet3: use-after-free in vmxnet3_rq_alloc_rx_buf()
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 •
CVE-2023-39418 – Postgresql: merge fails to enforce update or select row security policies
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 •
CVE-2023-39417 – Postgresql: extension script @substitutions@ within quoting allow sql injection
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') •
CVE-2022-40982 – hw: Intel: Gather Data Sampling (GDS) side channel vulnerability
https://notcve.org/view.php?id=CVE-2022-40982
Information exposure through microarchitectural state after transient execution in certain vector execution units for some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access. La exposición de información a través del estado microarquitectónico tras la ejecución transitoria en determinadas unidades de ejecución vectorial de algunos procesadores Intel(R) puede permitir a un usuario autenticado la divulgación potencial de información a través del acceso local. A Gather Data Sampling (GDS) transient execution side-channel vulnerability was found affecting certain Intel processors. This issue may allow a local attacker using gather instruction (load from memory) to infer stale data from previously used vector registers on the same physical core. • http://www.intel.com/content/www/us/en/security-center/advisory/intel-sa-00828.html https://access.redhat.com/solutions/7027704 https://aws.amazon.com/security/security-bulletins/AWS-2023-007 https://downfall.page https://lists.debian.org/debian-lts-announce/2023/08/msg00013.html https://lists.debian.org/debian-lts-announce/2023/08/msg00026.html https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/HKKYIK2EASDNUV4I7EFJKNBVO3KCKGRR https://lists.fedoraproject.org • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-203: Observable Discrepancy CWE-1342: Information Exposure through Microarchitectural State after Transient Execution •
CVE-2023-4273 – Kernel: exfat: stack overflow in exfat_get_uniname_from_ext_entry
https://notcve.org/view.php?id=CVE-2023-4273
A flaw was found in the exFAT driver of the Linux kernel. The vulnerability exists in the implementation of the file name reconstruction function, which is responsible for reading file name entries from a directory index and merging file name parts belonging to one file into a single long file name. Since the file name characters are copied into a stack variable, a local privileged attacker could use this flaw to overflow the kernel stack. Se ha encontrado un fallo en el controlador exFAT del núcleo de Linux. La vulnerabilidad se encuentra en la implementación de la función de reconstrucción de nombres de archivo, que se encarga de leer entradas de nombres de archivo de un índice de directorio y fusionar partes de nombres de archivo pertenecientes a un archivo en un único nombre de archivo largo. • https://access.redhat.com/errata/RHSA-2023:6583 https://access.redhat.com/security/cve/CVE-2023-4273 https://bugzilla.redhat.com/show_bug.cgi?id=2221609 https://dfir.ru/2023/08/23/cve-2023-4273-a-vulnerability-in-the-linux-exfat-driver https://lists.debian.org/debian-lts-announce/2023/10/msg00027.html https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/344H6HO6SSC4KT7PDFXSDIXKMKHISSGF https://lists.fedoraproject.org/archives/list/package-announce@lists.fedorapr • CWE-121: Stack-based Buffer Overflow CWE-787: Out-of-bounds Write •
