CVE-2007-3794
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedBuffer overflow in Hitachi Cosminexus V4 through V7, Processing Kit for XML before 20070511, Developer's Kit for Java before 20070312, and third-party products that use this software, allows attackers to have an unknown impact via certain GIF images, related to use of GIF image processing APIs by a Java application.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceBuffer overflow vulnerability in Hitachi Cosminexus V4-V7 and related Java development kits allows remote code execution through maliciously crafted GIF images processed by Java application APIs.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify installed Hitachi Cosminexus productLocate the Cosminexus installation directory and check for version information files or use system inventory tools. Common locations include /opt/hitachi or Windows Program Files目录下. Look for version.txt, install.info, or product metadata files that enumerate installed Hitachi software.Affected if Any Cosminexus Application Server, Client, Developer, Server, Studio, or Ucosminexus product is installed with a version matching the affected list
-
Verify product version against affected listCompare the installed version string (format like 05_00_05_00_h, 06_50_06_50_e, 07_00_07_20, etc.) against the specific versions listed in the CVE. The affected versions are: Application Server (05_00_05_00_h through 06_51_06_51_g), Client (06_00_06_00_g through 06_51_06_51_g), Developer (05_00_05_00_h through 06_51_06_51_g), Server (04_00_04_00_a, 04_01_04_01_a), Studio (04_00_04_00_a through 05_05_05_05_o), Ucosminexus Application Server (06_70_06_70_a through 07_10), Ucosminexus Client (06_70_06_70_b through 07_00_07_20), Ucosminexus Developer (06_70_06_70_b, 06_71_06_71_b).Affected if Installed version exactly matches any version in the CVE affected list
-
Determine if Java application processes GIF imagesInspect deployed Java applications for code that uses Java2D Image I/O APIs (javax.imageio) to process GIF files. Check application logs, configuration, or source code for ImageIO.read() calls with GIF files, or usage of java.awt.Image and Graphics2D drawImage() on GIF input.Affected if Java applications running on the Cosminexus platform process user-supplied or network-received GIF image files through Java Image I/O APIs
-
Check for exposed network interfaces accepting GIF uploadsReview web application endpoints, file upload handlers, or APIs that accept image uploads. Look for servlets, JSPs, or JAX-WS/JAX-RS endpoints that handle multipart form data containing images and process them server-side.Affected if Network-accessible endpoints accept GIF file uploads or process GIF images from untrusted sources
Environment is affected if a Hitachi Cosminexus or Ucosminexus product from the exact version list is installed AND the Java runtime processes GIF images from potentially untrusted sources through the Image I/O APIs.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedUpgrade Processing Kit for XML to version after 20070511 and Developer's Kit for Java to version after 20070312, or apply vendor-supplied patches to address the GIF processing buffer overflow.
Latest supported version of Cosminexus/Ucosminexus (contact Hitachi for current supported releases, as the affected V4-V7 versions are legacy)
- 1. Identify the exact Cosminexus/Ucosminexus product and version currently deployed using system inventory or version check utilities
- 2. Navigate to the official Hitachi Support portal (www.hitachi-support.com) and locate the security advisories for CVE-2007-3794
- 3. Download the applicable patch or hotfix for your specific product version - the description references fixes released after 20070511 (Processing Kit for XML) and after 20070312 (Developer's Kit for Java)
- 4. Apply the vendor-provided patch following Hitachi's installation instructions documented in the patch release notes
- 5. After patching, restart the affected services and verify the version reflects the patched release
- 6. Test that GIF image processing functionality works correctly with the patched version
- 7. Monitor Hitachi security advisories for any subsequent updates to this vulnerability
