App crash or memory disclosure via PostScript processing
Published Sep 23, 2022 · Updated May 27, 2025
Out-of-bounds write in PS Normalizer in Apple macOS allows local users to crash apps or disclose process memory via a PostScript file. PS Normalizer fails to enforce bounds while processing attacker-controlled PostScript data, permitting a write beyond the intended buffer. A user must cause the crafted file to be processed; the documented consequences are app termination and process-memory disclosure.
