Process crash via crafted OpenType font
Published Aug 16, 2022 · Updated Aug 3, 2024
Heap-buffer overflow in OTFCC 0.10.4 allows context-dependent attackers to crash otfccdump by supplying a crafted OpenType font. The public record identifies only offset 0x61731f in the release-x64 otfccdump binary and does not disclose the parser function or faulty write. Exploitation requires a user or application to process the crafted font, and the published impact is a process crash without reported data disclosure or modification.
