CVE-2026-25968
Description
A flaw was found in ImageMagick. A remote attacker could exploit a stack buffer overflow vulnerability by providing a specially crafted image file with a long attribute value. This flaw occurs when processing an attribute in msl.c, leading to memory corruption. This can result in unpredictable behavior or a denial of service.
Statement
A MODERATE impact stack buffer overflow flaw exists in ImageMagick. This vulnerability occurs when processing a specially crafted image file containing a long attribute value, leading to memory corruption, unpredictable behavior, or a denial of service. This affects ImageMagick as shipped in Red Hat Enterprise Linux, Fedora, and Community Projects, requiring the processing of a malicious image file for exploitation.
Mitigation
To reduce the risk associated with this vulnerability, avoid processing untrusted or maliciously crafted image files with ImageMagick. If ImageMagick is not required for system operations, consider removing packages that depend on it. Removing ImageMagick or its dependent packages may affect applications that rely on its image processing capabilities.
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.

Understanding the Weakness (CWE)
Integrity,Confidentiality,Availability
Technical Impact: Modify Memory; Execute Unauthorized Code or Commands
Buffer overflows often can be used to execute arbitrary code, which is usually outside the scope of the product's implicit security policy. This can often be used to subvert any other security service.
Availability
Technical Impact: Modify Memory; DoS: Crash, Exit, or Restart; DoS: Resource Consumption (CPU)
Buffer overflows generally lead to crashes. Other attacks leading to lack of availability are possible, including putting the product into an infinite loop.
