Calling a function that triggers a UI refresh after removing comments via a script may access an invalidated object, leading to program crashes.

Parsing logic flaws cause non-signature data to be misidentified as valid signatures when processing malformed form field hierarchies, leading to invalid memory writes and program crashes during internal data structure construction.

Document structural anomalies caused inconsistencies between page element relationships and internal index states. When scripts triggered document modifications, object reference validity was not properly maintained, leading to a crash when accessing an invalid pointer during page information queries.

Insufficient parameter verification leads to the occurrence of format errors in files, which will trigger an unhandled "std::invalidargument" exception, ultimately causing the program to terminate.

Improper control flow management allows a crafted document action chain to cause modal dialog reentry on the main thread, resulting in UI freeze and denial of service.

Flaws in page lifecycle management allow document structure changes to desynchronize internal component states, causing subsequent operations to access invalidated objects and crash the program.

A crafted XFA PDF can trigger a use-after-free condition during calculate event processing, causing the application to crash and resulting in an arbitrary code execution.
