CVE-2024-7867

Application crash via oversized page-box coordinates

Published Aug 15, 2024 · Updated Aug 16, 2024

Integer overflow and divide-by-zero in Xpdf 4.05 and earlier allow local users to crash a PDF-processing application with a crafted PDF. Page-box handling accepts extremely large coordinate values and uses them in integer size arithmetic that overflows and produces a zero divisor. Exploitation requires local processing of a malicious PDF and interrupts only the affected process, with no reported data disclosure or modification.
