CVE-2022-35030Network attack vector

Utility crash via malformed OpenType font

Published Sep 22, 2022 · Updated May 27, 2025

Out-of-bounds write in OTFCC otfccdump commit 617837b allows remote attackers to crash the utility via a crafted OpenType font. The public record identifies an offset in the release-x64 binary but does not disclose the parser function or unchecked write operation. Exploitation requires user interaction to pass the crafted font to otfccdump and interrupts only that process, with no reported data disclosure or modification.
