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 · unedited
An integer overflow (CWE-190) potentially causing an out-of-bounds read (CWE-125) vulnerability in Micro Focus VisiBroker 8.5 can lead to a denial of service.

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 confidence

Integer overflow vulnerability in Micro Focus VisiBroker 8.5 where improper integer arithmetic can cause memory corruption, leading to an out-of-bounds read condition. This can be exploited to cause a denial of service by crashing the affected service.

MitigationContact Micro Focus for the applicable patch or upgrade to a patched version of VisiBroker. If patching is not immediately possible, network segmentation and restricting access to the VisiBroker service can reduce exposure.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Confirm VisiBroker installation
    Locate VisiBroker installation directory or check for VisiBroker processes running on the system. Common locations include /opt/visibroker or installation under Micro Focus directories on Windows.
    Affected if VisiBroker software is present on the system
  2. Verify installed version is exactly 8.5
    Check the VisiBroker version using the product's version information utility, about dialog, or by inspecting version metadata in the installation directory. Compare against the affected version range = 8.5.
    Affected if Installed version is 8.5 exactly
  3. Identify VisiBroker service exposure
    Check which network ports VisiBroker is configured to listen on (typically IIOP ports). Use netstat or similar tools to identify listening services associated with VisiBroker processes.
    Affected if VisiBroker service is running and listening on network ports
  4. Assess network accessibility
    Review firewall rules and network configuration to determine if the VisiBroker service ports are accessible from network segments beyond what is intended for the application.
    Affected if VisiBroker ports are accessible to untrusted network segments

The environment is affected if Micro Focus VisiBroker version 8.5 is installed and its service is exposed on the network.
