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
Multiple heap-based buffer overflows in EMC RepliStor 6.2 SP2, and possibly earlier versions, allow remote attackers to execute arbitrary code via crafted compressed data.

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

Multiple heap-based buffer overflow vulnerabilities in EMC RepliStor 6.2 SP2 allow remote attackers to execute arbitrary code by sending crafted compressed data packets to the RepliStor service. The vulnerability lies in how the product processes compressed replication data, allowing overflow of heap-allocated buffers.

MitigationOrganizations should determine if EMC RepliStor is still in use, check for available patches or upgrades from EMC, and if the product is unsupported, migrate to a modern supported solution or apply strict network segmentation to limit exposure to the RepliStor service.

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. Check if EMC RepliStor is installed
    Look for RepliStor installation directories (typically C:\Program Files\EMC\RepliStor or similar) or check Windows Add/Remove Programs for EMC RepliStor entry
    Affected if EMC RepliStor software is present on the system
  2. Verify the installed RepliStor version
    Check the RepliStor version information in the software installation, typically found in the product GUI under Help > About, or check registry keys under HKLM\SOFTWARE\EMC\RepliStor for version strings
    Affected if The version is exactly 6.2_sp2 (this specific version is affected)
  3. Confirm the RepliStor service is running
    Open Windows Services console (services.msc) and look for the RepliStor service, or run 'sc query RepliStor' from command prompt
    Affected if The RepliStor service is running and accepting network connections
  4. Check if RepliStor listens on network ports
    Run 'netstat -an' or use 'netsh interface tcp show stats' to identify listening ports associated with RepliStor (typically TCP ports 1999, 2000, or 2001 by default)
    Affected if The RepliStor service is bound to accessible network interfaces

A system is affected if EMC RepliStor version 6.2_sp2 is installed and the RepliStor service is running and network-accessible, as the heap overflow requires the vulnerable compressed data processing code to be active.
