Attack-Flow Graph

Executive Summary

This vulnerability is an out-of-bounds write issue found in Acrobat Reader versions 24.001.30365, 26.001.21651 and earlier. It allows an attacker to write data outside the intended memory boundaries, which can lead to arbitrary code execution within the context of the current user.

Exploitation requires user interaction, meaning the victim must open a specially crafted malicious file to trigger the vulnerability.

Impact Analysis

If exploited, this vulnerability can allow an attacker to execute arbitrary code on your system with the privileges of the current user. This could lead to unauthorized actions such as installing malware, stealing data, or taking control of the affected system.
