MEDIUM

Stack exhaustion caused by cyclic references in Foxit PDF Editor/Reader

Title source: cna

Description

When pages and annotations are crafted that reference each other in a loop, passing the document to APIs (e.g., SOAP) that perform deep traversal can cause uncontrolled recursion, stack exhaustion, and application crashes.
