This vulnerability allows for a stack overflow in ImageMagick's `magick mogrify` command. The issue arises when specifying multiple consecutive `%d` format specifiers in a filename template, causing internal pointer arithmetic to generate an address below the beginning of the stack buffer. This vulnerability affects all versions prior to 7.1.2-0 and 6.9.13-26.
Severity is classified as high due to the CVSS score of 7.4, indicating a significant risk to applications that rely on ImageMagick for image processing. Organizations using vulnerable versions should prioritize patching immediately.
Risk to organizations includes potential exploitation leading to denial of service or unauthorized access to sensitive data. Although no known exploits are reported, the nature of the vulnerability poses a serious threat.
Organizations should address this vulnerability in priority patch cycle to mitigate the risk effectively.
Vulnerability Details
The vulnerability is described in CVE-2025-53101, where ImageMagick, a widely used open-source software for editing digital images, is impacted. The main issue lies in the `magick mogrify` command, where incorrect handling of format specifiers can lead to a stack overflow. The affected versions are all versions prior to 7.1.2-0 and 6.9.13-26.
The CVSS score is 7.4, indicating high severity. The vulnerability is classified under CWE-124, related to buffer errors. It is essential for organizations to ensure they are running the updated versions to avoid potential exploitation.
Technical Analysis
The root cause of this vulnerability is improper validation during pointer arithmetic within the `magick mogrify` command. This leads to the generation of addresses that fall below the stack buffer, resulting in a stack overflow when `vsnprintf()` is called. The attack vector is network-based, allowing remote attackers to exploit the vulnerability without requiring physical access.
The attack complexity is considered high due to the need for specific conditions to be met, such as crafting a filename template with multiple `%d` format specifiers. No user interaction is required, and the vulnerability impacts the integrity and availability of the system.
Risk & Impact Analysis
Deployment of vulnerable versions of ImageMagick can lead to significant operational risks. Exploitation may allow attackers to crash services or potentially execute arbitrary code, thereby compromising the integrity and availability of the system. The blast radius could be extensive, affecting all applications that utilize ImageMagick for image processing.
Given the high severity and potential impact, organizations should prioritize remediation efforts. The urgency assessment is high due to the availability of fixed versions, which addresses the vulnerability effectively.
