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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-190"],"references":["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"],"products":["postgresql:postgresql","redhat:codeready_linux_builder_eus","redhat:codeready_linux_builder_eus_for_power_little_endian_eus","redhat:codeready_linux_builder_for_arm64_eus","redhat:codeready_linux_builder_for_ibm_z_systems_eus","redhat:codeready_linux_builder_for_power_little_endian_eus","redhat:enterprise_linux","redhat:enterprise_linux_desktop","redhat:enterprise_linux_eus","redhat:enterprise_linux_for_arm_64","redhat:enterprise_linux_for_ibm_z_systems","redhat:enterprise_linux_for_ibm_z_systems_eus","redhat:enterprise_linux_for_power_big_endian","redhat:enterprise_linux_for_power_little_endian","redhat:enterprise_linux_for_power_little_endian_eus","redhat:enterprise_linux_for_scientific_computing","redhat:enterprise_linux_server","redhat:enterprise_linux_server_aus","redhat:enterprise_linux_server_tus","redhat:enterprise_linux_workstation","redhat:software_collections"],"source":"nvd","synced_at":"2026-10-19T21:42:34.585441961+00:00"},"epss":{"cve":"CVE-2023-5869","score":0.04322,"percentile":0.91178,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
