CVSS: 8.8EPSS: 1%CPEs: 49EXPL: 0CVE-2023-5869 – Postgresql: buffer overrun from integer overflow in array modification
https://notcve.org/view.php?id=CVE-2023-5869
A flaw was found in PostgreSQL that allows authenticated database users to execute arbitrary code through missing overflow checks during SQL array value modification. This issue exists due to an integer overflow during array modification where a remote user can trigger the overflow by providing specially crafted data. This enables the execution of arbitrary code on the target system, allowing users to write arbitrary bytes to memory and extensively read the server's memory. Se encontró una falla en PostgreSQL que permite a los usuarios de bases de datos autenticados ejecutar código arbitrario al faltar verificaciones de desbordamiento durante la modificación del valor de la matriz SQL. Este problema existe debido a un desbordamiento de enteros durante la modificación de la matriz, donde un usuario remoto puede desencadenar el desbordamiento proporcionando datos especialmente manipulados. • 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-190: Integer Overflow or Wraparound •
CVSS: 4.4EPSS: 0%CPEs: 42EXPL: 0CVE-2023-5870 – Postgresql: role pg_signal_backend can signal certain superuser processes.
https://notcve.org/view.php?id=CVE-2023-5870
A flaw was found in PostgreSQL involving the pg_cancel_backend role that signals background workers, including the logical replication launcher, autovacuum workers, and the autovacuum launcher. Successful exploitation requires a non-core extension with a less-resilient background worker and would affect that specific background worker only. This issue may allow a remote high privileged user to launch a denial of service (DoS) attack. Se encontró una falla en PostgreSQL que involucra la función pg_cancel_backend que señala a los trabajadores en segundo plano, incluido el iniciador de replicación lógica, los trabajadores de autovacuum y el iniciador de autovacuum. La explotación exitosa requiere una extensión no central con un trabajador en segundo plano menos resistente y afectaría únicamente a ese trabajador en segundo plano específico. • 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-400: Uncontrolled Resource Consumption •
