CVE-2007-6426
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 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 confidenceMultiple 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.

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.
-
Check if EMC RepliStor is installedLook for RepliStor installation directories (typically C:\Program Files\EMC\RepliStor or similar) or check Windows Add/Remove Programs for EMC RepliStor entryAffected if EMC RepliStor software is present on the system
-
Verify the installed RepliStor versionCheck 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 stringsAffected if The version is exactly 6.2_sp2 (this specific version is affected)
-
Confirm the RepliStor service is runningOpen Windows Services console (services.msc) and look for the RepliStor service, or run 'sc query RepliStor' from command promptAffected if The RepliStor service is running and accepting network connections
-
Check if RepliStor listens on network portsRun '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.

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 dataOrganizations 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.
