Handling 'unknown'-type values from string literals without type designation can disclose bytes, potentially revealing notable and confidential information. This issue exists due to excessive data output in aggregate function calls, enabling remote users to read some portion of system memory.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","score":4.3},"cwes":["CWE-686"],"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_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_little_endian","redhat:enterprise_linux_for_power_little_endian_eus","redhat:enterprise_linux_server_aus","redhat:enterprise_linux_server_tus","redhat:software_collections"],"source":"nvd","synced_at":"2026-10-19T21:42:34.585441961+00:00"},"epss":{"cve":"CVE-2023-5868","score":0.02775,"percentile":0.86351,"date":"2026-11-01"},"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).
