Name of the Vulnerable Software and Affected Versions Foxit PDF Editor/Reader (affected versions not specified)

Description A use-after-free issue occurs when the application opens a PDF and JavaScript modifies the form. Due to incomplete lifecycle management and a lack of null value validation for related objects on the page, the application continuously dereferences invalid objects during page state changes, resulting in a crash. Use-after-free is a condition where a program continues to use a pointer after it has been freed, which can lead to instability or memory corruption.
