Application crash via crafted OpenType font
Published Aug 16, 2022 · Updated Aug 3, 2024
Out-of-bounds read in OTFCC 0.10.4 allows attackers to crash otfccdump by processing a crafted OpenType font file. The public report exposes only a crashing memmove frame and does not identify the parser routine or unchecked field that supplies the invalid copy range. The file must be supplied to and processed by otfccdump; the documented consequence is process termination, with no supported confidentiality or integrity impact.
