Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-2 Flaw Remediation good match

prevent

Directly requires timely remediation by updating the vulnerable Android-ImageMagick7 library to version 7.1.2-11 or later to eliminate the integer overflow vulnerability.

RA-5 Vulnerability Monitoring and Scanning partial match

detect

Vulnerability scanning identifies systems using vulnerable versions of Android-ImageMagick7 affected by CVE-2026-33855.

SI-10 Information Input Validation partial match

prevent

Validates image file inputs prior to processing to block maliciously crafted images that trigger the integer overflow leading to denial of service.

MITRE ATT&CK Enterprise TechniquesAI

T1204.003 Malicious Image Execution

Adversaries may rely on a user running a malicious image to facilitate execution.

T1499.004 Application or System Exploitation Impact

Adversaries may exploit software vulnerabilities that can cause an application or system to crash and deny availability to users.

attack.mitre.org →

Why these techniques?

Integer overflow in image processing library enables DoS via crafted image requiring user interaction to open/process (T1204.003) and application exploitation for availability impact (T1499.004).

NVD Description

Integer Overflow or Wraparound vulnerability in MolotovCherry Android-ImageMagick7.This issue affects Android-ImageMagick7: before 7.1.2-11.

Deeper analysisAI

CVE-2026-33855 is an Integer Overflow or Wraparound vulnerability (CWE-190) in the MolotovCherry Android-ImageMagick7 library. This issue affects versions of Android-ImageMagick7 prior to 7.1.2-11. Published on 2026-03-24, it carries a CVSS v3.1 base score of 5.5 (AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H), indicating medium severity with primary impact on availability.

A local attacker requires no privileges but must rely on user interaction to exploit the vulnerability. By tricking a user into processing a maliciously crafted image file with the affected library, the attacker can trigger the integer overflow, resulting in a denial of service such as application crash or resource exhaustion, with no impact on confidentiality or integrity.

Mitigation is addressed in the GitHub pull request at https://github.com/MolotovCherry/Android-ImageMagick7/pull/187, which fixes the issue in version 7.1.2-11. Affected Android applications should update the Android-ImageMagick7 library to 7.1.2-11 or later to prevent exploitation.
