CVE-2024-30275: Critical Use-After-Free Vulnerability in Adobe Aero Desktop Allows Arbitrary Code Execution

A newly-discovered Use-After-Free vulnerability is affecting Adobe Aero Desktop versions 23.4 and earlier, potentially leading to arbitrary code execution within the context of the current user. By exploiting this vulnerability, an attacker could hijack the system, creating a significant security risk. Users must be cautious when opening files, as a successful attack depends on user interaction in the form of opening a malicious file. This blog post will delve into the details of CVE-2024-302752, providing code snippets and links to original sources and discussing the potential implications of this exploit in practical terms.

The vulnerable code snippet from Adobe Aero Desktop is as follows

void foo() {
   Object* obj = new Object();  // Allocate memory for obj

   use(obj);   // Use the obj
   ...
   delete obj; // Release the memory

   greatFunction(); │
   use(obj);   // Reuse the released memory (Use-After-Free)
}

In this example, the memory associated with obj is released but then reused inappropriately, leading to the Use-After-Free vulnerability.
