CVE-2026-30883
Description
A flaw was found in ImageMagick, a free and open-source software used for editing and manipulating digital images. A local attacker could exploit this vulnerability by providing an extremely large image profile when encoding a PNG image. This could result in a heap overflow, leading to a Denial of Service (DoS), which makes the affected system or application unavailable to legitimate users.
Statement
This MODERATE impact vulnerability in ImageMagick affects Red Hat Enterprise Linux 6 ELS and 7 ELS. A heap overflow can occur when processing an extremely large image profile during PNG encoding. Exploitation requires an attacker to provide a specially crafted image file for processing.
Mitigation
To mitigate this issue, avoid processing untrusted or maliciously crafted image files with ImageMagick. Users should exercise caution when handling image files from unknown or suspicious sources.
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.
