Local stack exhaustion via vfprintf
Published Aug 16, 2022 · Updated Aug 3, 2024
Stack overflow in SWFTools commit 772e55a2 allows local users to crash processing via crafted input to vfprintf. The vulnerable path reaches vfprintf in /stdio-common/vfprintf.c, where crafted data triggers stack exhaustion during formatting. Exploitation requires local execution and user interaction with malicious input; impact is limited to availability, with no reported confidentiality or integrity loss.
