CVE-2024-47456
📋 TL;DR
Adobe Illustrator versions 28.7.1 and earlier contain an out-of-bounds read vulnerability that could allow attackers to read sensitive memory contents. This could potentially bypass security mitigations like ASLR, though exploitation requires a user to open a malicious file. Users of affected Illustrator versions 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 bypassing ASLR to enable more sophisticated attacks or leak confidential data from the application's memory space.
Likely Case
Limited information disclosure from memory, potentially revealing some application data but unlikely to lead to full system compromise without additional vulnerabilities.
If Mitigated
With proper controls, the impact is minimal as exploitation requires user interaction and the vulnerability only allows reading, not writing, to memory.
🎯 Exploit Status
Exploitation requires user interaction (opening malicious file) and knowledge of memory layout. No public exploits known at this time.
