CVE-2023-26352
📋 TL;DR
Adobe Dimension versions 3.4.7 and earlier contain an out-of-bounds read vulnerability that could allow attackers to read sensitive memory contents. This could help bypass security mitigations like ASLR, potentially enabling further exploitation. Users who open malicious files with affected versions are at risk.
💻 Affected Systems
- Adobe Dimension
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
An attacker could leverage the memory disclosure to bypass ASLR and chain with other vulnerabilities for arbitrary code execution, potentially gaining full system control.
Likely Case
Memory disclosure that reveals sensitive information, which could be used to facilitate more sophisticated attacks against the system.
If Mitigated
Limited information disclosure with no direct code execution, though still providing attackers with useful memory layout information.
🎯 Exploit Status
Exploitation requires user interaction (opening malicious file) and knowledge of memory layout. No public exploits known at this time.
