CWE ID Description
CWE-416 The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.

Executive Summary

This vulnerability is a Use After Free issue found in certain versions of Acrobat Reader (24.001.30307, 24.001.30308, 25.001.21265 and earlier). It occurs when the program attempts to use memory after it has been freed, which can lead to unexpected behavior.

An attacker can exploit this vulnerability by tricking a user into opening a specially crafted malicious file, which then allows the attacker to execute arbitrary code with the same privileges as the current user.

Impact Analysis

If exploited, this vulnerability can allow an attacker to run arbitrary code on your system with the privileges of the user who opened the malicious file.

This could lead to unauthorized actions such as installing malware, stealing data, or taking control of your system.

However, exploitation requires user interaction, meaning the victim must open a malicious file for the attack to succeed.
