CVE-2025-32364Public exploit

Application crash via INT_MIN stack-count negation

Published Apr 5, 2025 · Updated Nov 3, 2025

Integer overflow in PSStack::roll in freedesktop.org Poppler before 25.04.0 allows local users to crash applications via malformed PDF input. When the stack-rotation count is INT_MIN, PSStack::roll negates it before applying modulo, overflowing the signed integer and raising a floating-point exception. Processing such a file terminates the Poppler-based process, limiting the established impact to a service interruption without reported data access or modification.
