{"id":"AZL-95711","summary":"CVE-2026-16241 affecting package postgresql 16.14-1","details":"Integer underflow in PostgreSQL ECPG allows a database server administrator to achieve temporary denial of service against the ECPG client via sending a bytea value lacking the mandatory prefix.  The client overwrites a huge memory region with bytes outside attacker knowledge or control.  This typically yields a simple SIGSEGV, but rare cases might achieve client-specific integrity impact via the write.  Versions before PostgreSQL 18.6, 17.11, 16.15, 15.19, and 14.24 are affected.","modified":"2026-09-04T05:27:10Z","published":"2026-08-13T13:17:46Z","upstream":["CVE-2026-16241"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-16241"}],"affected":[{"package":{"name":"postgresql","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/postgresql"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"16.14-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-95711.json"}}],"schema_version":"1.9.0"}
