CVE-2026-4152
Description
A flaw was found in GIMP. A remote attacker could exploit this by tricking a user into opening a specially crafted JP2 (JPEG 2000) file. This flaw is due to a heap-based buffer overflow during JP2 file parsing, which allows for arbitrary code execution. Successful exploitation enables the attacker to execute code in the context of the current process.
Statement
This is an Important vulnerability in GIMP that could lead to arbitrary code execution. The flaw is a heap-based buffer overflow in the JP2 file parsing component. Exploitation requires user interaction, where a victim must open a specially crafted malicious JP2 file.
Mitigation
To mitigate this issue, users should avoid opening JP2 (JPEG 2000) files from untrusted sources in GIMP. If GIMP is not required, consider removing the `gimp` package to eliminate the attack surface. For systems where GIMP is necessary, running the application within a sandboxed environment can limit the potential impact of successful exploitation. Removing this package may affect other applications that depend on GIMP.
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).

Understanding the Weakness (CWE)
Integrity,Availability,Confidentiality
Technical Impact: DoS: Crash, Exit, or Restart; Execute Unauthorized Code or Commands; Read Memory; Modify Memory
If the incorrect calculation is used in the context of memory allocation, then the software may create a buffer that is smaller or larger than expected. If the allocated buffer is smaller than expected, this could lead to an out-of-bounds read or write (CWE-119), possibly causing a crash, allowing arbitrary code execution, or exposing sensitive data.
