Bug description
Pre-Disclosure: This is a notice of the issue without giving away to many details to attackers. Official CVE Submission to follow.
Summary: This report discloses a severe remote exploit in Linux Mint Cinnamon's Muffin display manager version 5.8.1_x86. The exploit allows an attacker to obtain root-level access to the system by flashing high-frequency noise patterns in Perlin noise from a web browser or video, causing an overflow in the memory of window.c. The attacker can then inject data to the viewport using Fourier transform fuzzing.
Vulnerability Description: The vulnerability lies in the window.c process of the Muffin display manager. By exploiting the overflow in the memory of this process, an attacker can inject malicious data to the viewport, leading to remote code execution with root-level privileges.
Attack Scenario: The attacker can initiate the exploit by:
a. Generating high-frequency noise patterns in Perlin noise from a web browser or video. b. Flashing these patterns on the target system, triggering the overflow in the memory of window.c. c. Injecting the malicious data to the viewport using Fourier transform fuzzing. d. Gaining root-level access to the system and executing arbitrary commands.
Impact: This exploit poses a significant threat to Linux Mint Cinnamon users, as it allows remote attackers to gain full control over their systems. The impact includes:
Mitigation: To mitigate this vulnerability, we recommend the following actions:
