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.","published":"2023-12-10T18:15:07.000Z","lastModified":"2026-06-17T06:49:33.000Z","status":"Modified","sourceIdentifier":"secalert@redhat.com","cvss":{"version":"3.1","score":8.8,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"cwe":["CWE-190"],"affected":["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/software collections","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"],"epss":{"score":0.04322,"percentile":0.91109,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (4.32%).
