CVE-2025-14423
Description
A flaw was found in GIMP. This stack-based buffer overflow vulnerability occurs during the parsing of LBM files due to insufficient validation of user-supplied data length. A remote attacker can exploit this by tricking a user into opening a specially crafted malicious LBM file. Successful exploitation could lead to arbitrary code execution in the context of the current process.
Statement
This vulnerability is rated Important for Red Hat products as it allows for remote code execution in GIMP. Exploitation requires user interaction, specifically tricking a user into opening a specially crafted malicious LBM file.
Mitigation
To mitigate this vulnerability, users should avoid opening untrusted LBM files with GIMP. If GIMP is not essential for system operation, consider removing the `gimp` package to eliminate the attack surface. This can be done using the system's package manager. For example, on Red Hat Enterprise Linux, use `sudo yum remove gimp` or `sudo dnf remove 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)
Availability
Technical Impact: Modify Memory; DoS: Crash, Exit, or Restart; DoS: Resource Consumption (CPU); DoS: Resource Consumption (Memory)
Buffer overflows generally lead to crashes. Other attacks leading to lack of availability are possible, including putting the program into an infinite loop.
Integrity,Confidentiality,Availability,Access Control
Technical Impact: Modify Memory; Execute Unauthorized Code or Commands; Bypass Protection Mechanism
Buffer overflows often can be used to execute arbitrary code, which is usually outside the scope of a program's implicit security policy.
Integrity,Confidentiality,Availability,Access Control,Other
Technical Impact: Modify Memory; Execute Unauthorized Code or Commands; Bypass Protection Mechanism; Other
When the consequence is arbitrary code execution, this can often be used to subvert any other security service.
