CVE-2026-4153
Description
A flaw was found in GIMP. A remote attacker could exploit this vulnerability by enticing a user to open a specially crafted PSP (PaintShop Pro) file. This flaw is caused by a heap-based buffer overflow, where the application does not properly validate the length of user-supplied data. Successful exploitation can lead to arbitrary code execution in the context of the current process.
Statement
This is an Important vulnerability in GIMP that could lead to arbitrary code execution. The flaw requires user interaction, as an attacker must entice a user to open a specially crafted PSP (PaintShop Pro) file. Red Hat products are affected if GIMP is installed and used to open untrusted PSP files.
Mitigation
To mitigate this vulnerability, users should avoid opening untrusted PSP (PaintShop Pro) files with GIMP. Restricting the sources of PSP files to only trusted origins can reduce the risk of exploitation.
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,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.
