DescriptionCVE.org

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 6.9.13-51 and 7.1.2-26, an integer overflow in the XCF decoder can result in an out of bounds read when a crafted image is read, potentially resulting in a crash. This issue has been fixed in versions 6.9.13-51 and 7.1.2-26.

AnalysisAI

Integer overflow in ImageMagick's XCF (GIMP native format) decoder allows remote unauthenticated attackers to trigger an out-of-bounds read by supplying a crafted XCF image file, resulting in an application crash or limited memory disclosure. All ImageMagick releases prior to 6.9.13-51 (legacy branch) and 7.1.2-26 (current branch) are affected. …

Vulnerability AssessmentAI

Exploitation The vulnerable code path requires that the target system invoke the ImageMagick XCF image decoder on attacker-controlled input - meaning the application must accept XCF-format files, or lack format validation that would block them before decoding. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The NVD-assigned CVSS 3.1 score of 6.5 (Medium) with vector AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:L accurately characterizes the attack surface: the flaw is reachable over a network with no authentication, no user interaction, and low attack complexity, making it broadly automatable. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker submits a specially crafted XCF image file to a web application, API endpoint, or image-processing pipeline that passes user-supplied files to ImageMagick. The malformed XCF triggers the integer overflow in the decoder, which causes an out-of-bounds read - either crashing the ImageMagick worker process (denial of service) or, in a more targeted scenario, leaking a small region of heap memory that could contain session tokens or other sensitive data processed nearby. …
Remediation Upgrade ImageMagick to version 6.9.13-51 or later (for 6.x deployments) or to version 7.1.2-26 or later (for 7.x deployments), as confirmed by the vendor security advisory at https://github.com/ImageMagick/ImageMagick/security/advisories/GHSA-pjxj-pchx-4c3m. … Detailed patch versions, workarounds, and compensating controls in full report.
