Description The issue is related to a Heap-based Buffer Overflow when parsing a specially crafted file, allowing an unauthenticated attacker to achieve arbitrary code execution in the context of the current user. Exploitation requires user interaction, where a victim must open a malicious file.

Recommendations For Adobe After Effects version 18.2 and earlier, update to a version that is not affected by this issue.
