CVE-2024-34135
📋 TL;DR
Adobe Illustrator versions 28.5, 27.9.4 and earlier contain an out-of-bounds read vulnerability that could allow attackers to read sensitive memory contents when users open malicious files. This could potentially bypass security mitigations like ASLR. Users of affected Illustrator versions who open untrusted files are at risk.
💻 Affected Systems
- Adobe Illustrator
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
An attacker could read sensitive memory contents, potentially extracting credentials, encryption keys, or other confidential data, and bypass ASLR to enable further exploitation.
Likely Case
Limited information disclosure from memory, potentially revealing some system information but unlikely to lead to full system compromise without additional vulnerabilities.
If Mitigated
With proper controls, the impact is limited to potential memory information leakage without code execution.
🎯 Exploit Status
Exploitation requires user interaction (opening malicious file) and knowledge of memory layout. No public exploits known at this time.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Update to Illustrator 28.6 or later
Vendor Advisory: https://helpx.adobe.com/security/products/illustrator/apsb24-45.html

Instructions:
1. Open Adobe Creative Cloud application. 2. Navigate to 'Apps' tab. 3. Find Adobe Illustrator. 4. Click 'Update' button. 5. Restart Illustrator after update completes.
🔧 Temporary Workarounds
Restrict file opening
allOnly open Illustrator files from trusted sources and avoid opening files from unknown or untrusted sources.
Use application sandboxing
allRun Illustrator in a sandboxed environment to limit potential impact of memory reads.
🧯 If You Can't Patch
- Implement strict file handling policies to prevent opening untrusted Illustrator files
- Use endpoint detection and response (EDR) tools to monitor for suspicious file opening behavior
