ImageMagick, a widely used free and open-source software for editing and manipulating digital images, is vulnerable to a heap-buffer overflow prior to version 7.1.2-1. This vulnerability arises from improper handling of images with separate alpha channels during image magnification in the ReadOneMNGImage function. Attackers may leverage this vulnerability to leak subsequent memory contents into the output image, posing a significant risk to the confidentiality of sensitive data.
The common vulnerability scoring system (CVSS) has assigned a score of 7.6 to this issue, categorizing it as high severity. The attack vector is network-based, requiring low complexity and no privileges to exploit, but it does necessitate user interaction. This makes the vulnerability particularly concerning as it could be exploited through maliciously crafted image files.
Organizations using ImageMagick should prioritize patching to version 7.1.2-1 or later, as this patch addresses the vulnerability. Delaying remediation could lead to unauthorized access to sensitive information, which could have severe implications for organizations relying on ImageMagick for image processing.
Currently, there are no known public exploitations of this vulnerability, but a proof of concept (PoC) has been found in a GitHub repository, indicating potential for future exploitation. The urgency for defenders is high, and immediate action is required.
Risk to organizations includes possible data leaks and compromised integrity of the images processed by ImageMagick. Organizations should address this vulnerability in their priority patch cycle to mitigate risk.
Vulnerability Details
Description: This vulnerability allows for a heap-buffer overflow read around the handling of images with separate alpha channels when performing image magnification in ReadOneMNGImage. This issue has been patched in version 7.1.2-1.
CVSS Score: 7.6 (High Severity) - This score indicates significant potential impact on the confidentiality of data processed through ImageMagick.
Affected Product: ImageMagick (all versions prior to 7.1.2-1).
CWE Classification: CWE-122.
Technical Analysis
The root cause of this vulnerability stems from the improper management of memory in the ReadOneMNGImage function when processing images with separate alpha channels. The attack vector is through network-based interactions, where an attacker could send specially crafted image files to a victim. The attack complexity is low, meaning that it does not require advanced skills to exploit.
No privileges are required to exploit this vulnerability, and user interaction is needed, as a user must open or process the malicious image file. The potential impacts include high confidentiality impact due to the leakage of sensitive information, low integrity impact, and low availability impact.
Risk & Impact Analysis
The risk to organizations includes potential data leaks that could expose sensitive information processed by ImageMagick. Given that this vulnerability can be triggered through network interactions, attackers may exploit this vulnerability to gain unauthorized access to sensitive data, leading to reputational harm and financial loss.
Organizations should prioritize addressing this vulnerability promptly, as the potential impact of exploitation is significant, particularly for those handling sensitive image data. The urgency for remediation is high, and organizations should ensure their ImageMagick installations are updated to the latest version.

|---|---|
Known Exploit | Yes |
Public PoC | Yes |
Actively Exploited | No |
Ransomware Use | No |
Affected Versions
All versions of ImageMagick prior to 7.1.2-1 are affected. Organizations should ensure they update to this version or later to mitigate the risk associated with this vulnerability.
Mitigation & Remediation
Organizations should prioritize patching ImageMagick to version 7.1.2-1 or later. If immediate patching is not possible, organizations may consider implementing temporary workarounds such as restricting the processing of untrusted image files until the patch can be applied.
For detailed guidance on securing ImageMagick installations, organizations may refer to application security assessments to identify potential vulnerabilities.
Detection Guidance
Organizations should monitor logs for unusual access patterns or attempts to process corrupted image files as indicators of exploitation. Additionally, behavioral anomalies during image handling may signal exploitation attempts.
