CVE-2022-35026Public exploitNetwork attack vector

Utility crash via out-of-bounds parser write

Published Sep 22, 2022 · Updated May 27, 2025

Out-of-bounds write in OTFCC otfccdump commit 617837b allows attackers to crash the utility via a crafted font file. Public records identify the failing locus only as otfccdump offset 0x4fbc0b and do not disclose the parser routine or unchecked field that causes the invalid write. Exploitation requires a user to process the file; the published impact is limited to termination of the otfccdump process, with no disclosed data access or code execution.
