Executive Summary

This vulnerability affects Adobe Illustrator versions 29.8.4, 30.1 and earlier. It is an out-of-bounds write vulnerability, which means that the software writes data outside the boundaries of allocated memory. This flaw could allow an attacker to execute arbitrary code with the privileges of the current user.

Exploitation requires user interaction, specifically that the victim must open a malicious file crafted to trigger the vulnerability.

Impact Analysis

If exploited, this vulnerability can lead to arbitrary code execution in the context of the current user. This means an attacker could potentially run malicious code on your system with your user privileges.

The impact includes potential compromise of confidentiality, integrity, and availability of your data and system, as indicated by the CVSS score which rates confidentiality, integrity, and availability impacts as high.

However, exploitation requires that you open a malicious file, so user caution can help mitigate risk.
