CVE-2018-20506: SQLite before 3.25.3, when the FTS3 extension is enabled, encounters an integer overflow (and resultant buf...

Security readout for executives and security teams

This flaw affects older SQLite builds when the FTS3 full-text search extension is enabled. If an attacker can run arbitrary SQL, they may be able to corrupt memory through crafted FTS3 shadow-table changes and potentially execute code. Exposure is narrower than a normal remote service bug because the attacker needs SQL execution capability first. Systems embedding SQLite versions before 3.25.3 with FTS3 enabled are the main concern. Risk is highest where untrusted users can influence or execute SQL, such as exposed WebSQL-like functionality or application scripting paths. Prioritize remediation for internet-facing or user-scriptable applications that embed old SQLite and expose SQL execution paths. For ordinary internal applications with no arbitrary SQL path, treat as a controlled upgrade risk rather than an emergency. Mitigation focus: Upgrade embedded SQLite to 3.25.3 or later where feasible.; Apply relevant vendor security updates for products bundling SQLite.; Check vendor guidance for platforms where SQLite is supplied by the OS..
