Arbitrary code execution via crafted files
Published May 21, 2020 · Updated Aug 19, 2026
Memory corruption in the Microsoft Windows Jet Database Engine allows context-dependent attackers to execute arbitrary code via crafted files. Microsoft has disclosed only that the engine improperly handles objects in memory, without identifying the affected routine or incorrect memory operation. Execution requires a victim to open a crafted file, after which attacker-controlled code runs in the victim's security context.
