CVE-2007-4758
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 · uneditedMultiple buffer overflows in the image-processing APIs in Cosminexus Developer's Kit for Java in Cosminexus 4 through 7 allow remote attackers to cause a denial of service or execute arbitrary code via unspecified vectors.
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 · moderate confidenceMultiple buffer overflow vulnerabilities exist in image-processing APIs of Cosminexus Developer's Kit for Java (versions 4-7), a proprietary enterprise Java development kit. Remote attackers can exploit unspecified vectors in image processing to overflow buffers, potentially achieving arbitrary code execution or causing denial of service.

It rates how the flaw is reached, what it takes to exploit, and what an attacker gains — the score is derived from those, not the other way round.

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 Cosminexus installationSearch for Cosminexus or Ucosminexus directories on the system, or check running Java processes for Cosminexus classpath entriesAffected if Cosminexus product directories or processes are found on the system
-
Determine installed versionCheck version information in the Cosminexus installation (typically in a version file, README, or productinfo directory within the installation root)Affected if The installed version matches any of: 07_00, 07_00_01, 07_00_02, 07_00_03, 07_10, 07_10_01, 7_20, 7_20_01, 07_20
-
Verify image processing API usageInspect running Java applications for usage of image processing libraries or classes (javax.imageio, java.awt.image, or proprietary Cosminexus image APIs)Affected if Applications are processing image data using Cosminexus Java APIs
-
Check network exposureReview firewall rules and network configuration to determine if the image processing services are accessible from networkAffected if Image processing endpoints are exposed to untrusted network sources
A user is affected if they have any of the listed Cosminexus versions installed AND are using the vulnerable image processing functionality accessible from their applications.

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.
From vendor dataObtain and apply vendor patches from NEC/HP for Cosminexus, or upgrade to a version beyond 7 that receives security updates. If the product is unsupported, migrate to a standard Java development environment with current security patches.
