CVE-2026-25989
Description
A flaw was found in ImageMagick, a software used for editing and manipulating digital images. A remote attacker could exploit an off-by-one boundary check vulnerability by providing a specially crafted SVG (Scalable Vector Graphics) file. This could lead to a denial of service (DoS) condition, making the software unavailable to legitimate users.
Statement
This is a MODERATE impact flaw in ImageMagick that could lead to a denial of service when processing a specially crafted SVG file. Red Hat Enterprise Linux 6 ELS and 7 ELS, as well as Community Projects like Fedora and EPEL, include ImageMagick. Exploitation requires an attacker to provide a malicious SVG file to a system utilizing ImageMagick for image processing.
Mitigation
To mitigate this issue, avoid processing untrusted SVG files with ImageMagick. If ImageMagick is used in an automated or server-side context, consider implementing sandboxing mechanisms or restricting the input sources to trusted origins to limit exposure to specially crafted SVG files.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
CVSS v3 Score Breakdown
| Red Hat | NVD | cve.org | |
|---|---|---|---|
| Base Score | 7.5 | N/A | 7.5 |
| Attack Vector | Network | N/A | Network |
| Attack Complexity | Low | N/A | Low |
| Privileges Required | None | N/A | None |
| User Interaction | None | N/A | None |
| Scope | Unchanged | N/A | Unchanged |
| Confidentiality | None | N/A | None |

Understanding the Weakness (CWE)
Availability
Technical Impact: DoS: Crash, Exit, or Restart; DoS: Resource Consumption (CPU); DoS: Resource Consumption (Memory); DoS: Instability
This weakness will generally lead to undefined behavior and therefore crashes. In the case of overflows involving loop index variables, the likelihood of infinite loops is also high.
Integrity
Technical Impact: Modify Memory
If the value in question is important to data (as opposed to flow), simple data corruption has occurred. Also, if the wrap around results in other conditions such as buffer overflows, further memory corruption may occur.
Confidentiality,Availability,Access Control
Technical Impact: Execute Unauthorized Code or Commands; Bypass Protection Mechanism
This weakness can sometimes trigger buffer overflows which can be used to execute arbitrary code. This is usually outside the scope of a program's implicit security policy.
