## Technical details

The vulnerability is an out-of-bounds read (CWE-125) in Illustrator's file parsing logic. An attacker can craft a malicious Illustrator document that, when opened by a victim, triggers an out-of-bounds memory access, allowing unauthorized reading of adjacent memory contents. This requires user interaction (opening a file) to trigger. The vulnerability affects versions 29.8.4 and 30.1 and earlier. No patch information is currently available in the advisory text.
