This vulnerability allows for memory corruption in ImageMagick, a widely used open-source software for image editing and manipulation. Specifically, the issue arises when preparing to transform from Log to sRGB colorspaces. If the reference-black or reference-white value exceeds 1024, the logmap construction fails, leading to corruption beyond the allocated logmap buffer. This flaw has been patched in version 7.1.2-1. The CVSS score for this vulnerability is 5.5, indicating a medium severity level.
Risk to organizations includes potential denial of service due to high availability impact, as well as possible exploitation by local attackers. The exploitation status indicates that a proof of concept (PoC) has been made available on GitHub, demonstrating the vulnerability's existence and potential impact.
Given the nature of this vulnerability, it is imperative for organizations using ImageMagick to prioritize patching immediately. Delaying this action may expose systems to unnecessary risk, especially in environments where image processing is a critical function.
Organizations should validate their remediation strategies and ensure that all affected systems are updated to the latest version to mitigate potential risks associated with this vulnerability.
Vulnerability Details
ImageMagick is free and open-source software used for editing and manipulating digital images. The vulnerability affects versions prior to 7.1.2-1, which fails to properly handle cases during colorspace transformation. The CVSS score for this vulnerability is 5.5, categorized under medium severity. The affected product is ImageMagick, with a publication date of August 13, 2025. The relevant CWE classification is CWE-122, related to heap-based buffer overflow.
Technical Analysis
The root cause of this vulnerability lies in the logmap construction process. When the reference values exceed the expected limits, memory corruption occurs, leading to an overflow condition. The attack vector for this vulnerability is local, requiring users to have access to the system to exploit it. The complexity of the attack is low, with no privileges required and user interaction necessary.
The impacts of this vulnerability primarily affect availability, with no confidentiality or integrity impacts reported. Organizations relying on ImageMagick for critical image processing tasks should be aware of the potential disruption this flaw could cause.
Risk & Impact Analysis
Real-world deployment risks associated with this vulnerability include service disruptions and potential data processing failures. The urgency for organizations to address this vulnerability is high, given the medium severity rating and the availability of a public proof of concept. Organizations should evaluate the potential blast radius of this vulnerability, particularly in environments heavily reliant on ImageMagick for image processing.
The CVSS score of 5.5 indicates a moderate risk that necessitates prompt attention. Organizations should assess their patch management processes to ensure that they can respond swiftly to vulnerabilities of this nature, as delays could lead to exploitable conditions.
