Vulnerability Note VU#399896

GIMP integer overflow vulnerability

Overview

GIMP contains a vulnerability that may allow a remote attacker to execute code, or create a denial-of-service condition.

I. Description

The Photoshop Document (PSD) format is the native file format used by Adobe Photoshop. The GNU Image Manipulation Program (GIMP) can open and manipulate .psd files.

The GIMP contains an integer overflow that can result in a heap-based buffer overflow. An attacker may be able to trigger the overflow by convincing a user to open a specially crafted .psd file.

II. Impact

A remote, unauthenticated attacker may be able to execute arbitrary code, or create a denial-of-service condition.

III. Solution

Update

The Gimp team has released a patch that is available from their SVN tree. Note that many Linux distributions redistribute GIMP. Administrators who use a packaged version of GIMP should see their operating system vendor for updates.
