otfccdump process crash
Published Aug 16, 2022 · Updated Aug 3, 2024
Segmentation violation in OTFCC 0.10.4 allows context-dependent attackers to crash otfccdump through malformed font input. The public record identifies the fault only as glibc offset 0xbb384 and does not disclose the OTFCC function or invalid memory operation. Exploitation requires a user to make otfccdump parse attacker-controlled OpenType content, and the reported consequence is termination of that command-line process.
