Description Preview

Adobe Illustrator versions 26.5.2 (and earlier) and 27.2.0 (and earlier) contain a Use After Free (CWE-416) vulnerability. When exploited, this vulnerability could allow an attacker to execute arbitrary code in the context of the current user. The attack requires user interaction, specifically opening a malicious file crafted by the attacker.

Overview

This vulnerability (CVE-2023-26426) affects Adobe Illustrator and is classified as a Use After Free (UAF) vulnerability. In this type of vulnerability, the application continues to use a memory location after it has been freed, which can lead to the execution of arbitrary code. The severity is high as it could allow attackers to run malicious code with the same privileges as the user running Illustrator. For successful exploitation, an attacker would need to trick a user into opening a specially crafted malicious file.

Remediation

Users should update to the latest version of Adobe Illustrator as soon as possible. Adobe has released patches to address this vulnerability in their security bulletin APSB23-19. As a general security practice, users should exercise caution when opening files from untrusted sources, especially those received via email or downloaded from the internet. Organizations should implement security awareness training to help users identify potential phishing attempts that might deliver malicious Illustrator files.
