{"id":"ALPINE-CVE-2023-5870","details":"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.","modified":"2025-11-19T06:20:48.950481Z","published":"2023-12-10T18:15:07.643Z","upstream":["CVE-2023-5870"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2023-5870"}],"affected":[{"package":{"name":"postgresql14","ecosystem":"Alpine:v3.15","purl":"pkg:apk/alpine/postgresql14?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"14.10-r0"}]}],"versions":["10.0-r0","10.0-r1","10.1-r0","10.1-r1","10.1-r2","10.2-r0","10.3-r0","10.3-r1","10.4-r0","10.5-r0","11.0-r0","11.0-r1","11.1-r0","11.2-r0","11.2-r1","11.3-r0","11.3-r1","11.3-r2","11.4-r0","11.4-r1","11.5-r0","11.5-r1","11.5-r2","12.0-r0","12.0-r1","12.1-r0","12.1-r1","12.1-r2","12.2-r0","12.2-r1","12.2-r2","12.2-r3","12.3-r0","12.3-r1","12.3-r2","12.4-r0","12.4-r1","12.5-r0","12.5-r1","13.1-r0","13.1-r1","13.1-r2","13.2-r0","13.2-r1","13.2-r2","13.2-r3","13.2-r4","13.3-r0","13.3-r1","13.4-r0","13.4-r1","13.4-r2","14.0-r0","14.0-r2","14.0-r3","14.0-r4","14.0-r5","14.0-r6","14.1-r0","14.1-r1","14.1-r2","14.1-r3","14.1-r4","14.1-r5","14.2-r0","14.3-r0","14.4-r0","14.5-r0","14.7-r0","14.8-r0","14.9-r0","8.3.5-r0","8.3.7-r0","8.3.7-r1","8.3.7-r2","8.3.7-r3","8.4.0-r0","8.4.0-r1","8.4.0-r2","8.4.1-r0","8.4.1-r1","8.4.2-r0","8.4.2-r1","8.4.3-r0","8.4.3-r1","8.4.3-r2","8.4.3-r3","8.4.4-r0","9.0.1-r0","9.0.2-r0","9.0.3-r0","9.0.3-r1","9.0.4-r0","9.1.0-r0","9.1.0-r1","9.1.1-r0","9.1.1-r1","9.1.1-r2","9.1.2-r0","9.1.2-r1","9.1.2-r2","9.1.3-r0","9.1.4-r0","9.1.5-r0","9.2.0-r0","9.2.0-r1","9.2.1-r0","9.2.1-r1","9.2.1-r2","9.2.2-r0","9.2.3-r0","9.2.4-r0","9.3.0-r0","9.3.0-r1","9.3.0-r2","9.3.1-r0","9.3.2-r0","9.3.3-r0","9.3.3-r1","9.3.3-r2","9.3.4-r0","9.3.4-r1","9.3.5-r0","9.3.5-r1","9.4.0-r0","9.4.1-r0","9.4.1-r1","9.4.1-r2","9.4.1-r3","9.4.2-r0","9.4.3-r0","9.4.4-r0","9.4.5-r0","9.4.5-r1","9.5.0-r0","9.5.1-r0","9.5.2-r0","9.5.2-r1","9.5.2-r2","9.5.2-r3","9.5.2-r4","9.5.3-r0","9.5.3-r1","9.5.4-r0","9.6.0-r0","9.6.0-r1","9.6.1-r0","9.6.1-r1","9.6.2-r0","9.6.2-r1","9.6.2-r2","9.6.2-r3","9.6.2-r4","9.6.3-r0","9.6.4-r0","9.6.4-r1","9.6.5-r0","9.6.5-r1"],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-5870.json"}},{"package":{"name":"postgresql14","ecosystem":"Alpine:v3.16","purl":"pkg:apk/alpine/postgresql14?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"14.10-r0"}]}],"versions":["10.0-r0","10.0-r1","10.1-r0","10.1-r1","10.1-r2","10.2-r0","10.3-r0","10.3-r1","10.4-r0","10.5-r0","11.0-r0","11.0-r1","11.1-r0","11.2-r0","11.2-r1","11.3-r0","11.3-r1","11.3-r2","11.4-r0","11.4-r1","11.5-r0","11.5-r1","11.5-r2","12.0-r0","12.0-r1","12.1-r0","12.1-r1","12.1-r2","12.2-r0","12.2-r1","12.2-r2","12.2-r3","12.3-r0","12.3-r1","12.3-r2","12.4-r0","12.4-r1","12.5-r0","12.5-r1","13.1-r0","13.1-r1","13.1-r2","13.2-r0","13.2-r1","13.2-r2","13.2-r3","13.2-r4","13.3-r0","13.3-r1","13.4-r0","13.4-r1","13.4-r2","14.0-r0","14.0-r2","14.0-r3","14.0-r4","14.0-r5","14.0-r6","14.1-r0","14.1-r1","14.1-r2","14.1-r3","14.1-r4","14.1-r5","14.1-r6","14.1-r7","14.2-r0","14.2-r1","14.2-r2","14.2-r3","14.3-r0","14.4-r0","14.4-r1","14.5-r0","14.7-r0","14.8-r0","14.9-r0","8.3.5-r0","8.3.7-r0","8.3.7-r1","8.3.7-r2","8.3.7-r3","8.4.0-r0","8.4.0-r1","8.4.0-r2","8.4.1-r0","8.4.1-r1","8.4.2-r0","8.4.2-r1","8.4.3-r0","8.4.3-r1","8.4.3-r2","8.4.3-r3","8.4.4-r0","9.0.1-r0","9.0.2-r0","9.0.3-r0","9.0.3-r1","9.0.4-r0","9.1.0-r0","9.1.0-r1","9.1.1-r0","9.1.1-r1","9.1.1-r2","9.1.2-r0","9.1.2-r1","9.1.2-r2","9.1.3-r0","9.1.4-r0","9.1.5-r0","9.2.0-r0","9.2.0-r1","9.2.1-r0","9.2.1-r1","9.2.1-r2","9.2.2-r0","9.2.3-r0","9.2.4-r0","9.3.0-r0","9.3.0-r1","9.3.0-r2","9.3.1-r0","9.3.2-r0","9.3.3-r0","9.3.3-r1","9.3.3-r2","9.3.4-r0","9.3.4-r1","9.3.5-r0","9.3.5-r1","9.4.0-r0","9.4.1-r0","9.4.1-r1","9.4.1-r2","9.4.1-r3","9.4.2-r0","9.4.3-r0","9.4.4-r0","9.4.5-r0","9.4.5-r1","9.5.0-r0","9.5.1-r0","9.5.2-r0","9.5.2-r1","9.5.2-r2","9.5.2-r3","9.5.2-r4","9.5.3-r0","9.5.3-r1","9.5.4-r0","9.6.0-r0","9.6.0-r1","9.6.1-r0","9.6.1-r1","9.6.2-r0","9.6.2-r1","9.6.2-r2","9.6.2-r3","9.6.2-r4","9.6.3-r0","9.6.4-r0","9.6.4-r1","9.6.5-r0","9.6.5-r1"],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-5870.json"}},{"package":{"name":"postgresql14","ecosystem":"Alpine:v3.17","purl":"pkg:apk/alpine/postgresql14?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"14.10-r0"}]}],"versions":["10.0-r0","10.0-r1","10.1-r0","10.1-r1","10.1-r2","10.2-r0","10.3-r0","10.3-r1","10.4-r0","10.5-r0","11.0-r0","11.0-r1","11.1-r0","11.2-r0","11.2-r1","11.3-r0","11.3-r1","11.3-r2","11.4-r0","11.4-r1","11.5-r0","11.5-r1","11.5-r2","12.0-r0","12.0-r1","12.1-r0","12.1-r1","12.1-r2","12.2-r0","12.2-r1","12.2-r2","12.2-r3","12.3-r0","12.3-r1","12.3-r2","12.4-r0","12.4-r1","12.5-r0","12.5-r1","13.1-r0","13.1-r1","13.1-r2","13.2-r0","13.2-r1","13.2-r2","13.2-r3","13.2-r4","13.3-r0"
