Attack-Flow Graph

Executive Summary

This vulnerability affects Adobe After Effects versions 25.6 and earlier. It is an out-of-bounds read issue that occurs when the software parses a specially crafted file. This means the program reads data beyond the allocated memory structure, which can lead to unexpected behavior.

An attacker could exploit this vulnerability by tricking a user into opening a malicious file, which could then allow the attacker to execute code with the same privileges as the current user.

Impact Analysis

If exploited, this vulnerability can allow an attacker to execute arbitrary code on your system with the privileges of the user who opened the malicious file.

This could lead to unauthorized access, data theft, or further compromise of your system depending on the permissions of the affected user.

Mitigation Strategies

To mitigate this vulnerability, avoid opening files from untrusted or unknown sources in After Effects versions 25.6 and earlier.

Since exploitation requires user interaction by opening a crafted malicious file, exercising caution with file sources is critical.

Additionally, updating After Effects to a version later than 25.6 when a patch is available would be an effective mitigation step.
