Heap buffer overflow via otfccdump parsing
Published Oct 14, 2022 · Updated May 15, 2025
OTFCC heap buffer overflow in otfccdump through commit 617837b allows attackers to interrupt service via crafted font input. The record locates the flaw at /release-x64/otfccdump+0x6c0414 but does not disclose which parser operation performs the out-of-bounds heap write. Exploitation requires a victim to process attacker-controlled input; reported impact is high availability loss without confidentiality or integrity impact.
