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: 7.8EPSS: 17%CPEs: 18EXPL: 18CVE-2023-4911 – GNU C Library Buffer Overflow Vulnerability
https://notcve.org/view.php?id=CVE-2023-4911
A buffer overflow was discovered in the GNU C Library's dynamic loader ld.so while processing the GLIBC_TUNABLES environment variable. This issue could allow a local attacker to use maliciously crafted GLIBC_TUNABLES environment variables when launching binaries with SUID permission to execute code with elevated privileges. Se descubrió un desbordamiento del búfer en el cargador dinámico ld.so de la librería GNU C mientras se procesaba la variable de entorno GLIBC_TUNABLES. Este problema podría permitir que un atacante local utilice variables de entorno GLIBC_TUNABLES manipuladas con fines malintencionados al iniciar archivos binarios con permiso SUID para ejecutar código con privilegios elevados. Dubbed Looney Tunables, Qualys discovered a buffer overflow vulnerability in the glibc dynamic loader's processing of the GLIBC_TUNABLES environment variable. • https://github.com/leesh3288/CVE-2023-4911 https://github.com/ruycr4ft/CVE-2023-4911 https://github.com/guffre/CVE-2023-4911 https://github.com/NishanthAnand21/CVE-2023-4911-PoC https://github.com/RickdeJager/CVE-2023-4911 https://github.com/hadrian3689/looney-tunables-CVE-2023-4911 https://github.com/Green-Avocado/CVE-2023-4911 https://github.com/xiaoQ1z/CVE-2023-4911 https://github.com/Diego-AltF4/CVE-2023-4911 https://github.com/KernelKrise/CVE-2023-4911 https:/&# • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •
