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
A vulnerability was found in Microword eScan Antivirus 7.0.32 on Linux. It has been rated as problematic. Affected by this issue is the function removeExtraSlashes of the file /opt/MicroWorld/sbin/rtscanner of the component Folder Watch List Handler. The manipulation leads to stack-based buffer overflow. The attack needs to be approached locally. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

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

Stack-based buffer overflow in the removeExtraSlashes function of the rtscanner (real-time scanner) component in eScan Antivirus 7.0.32 on Linux. The function fails to properly validate path length when removing extra slashes from folder paths in the Watch List Handler, allowing a local attacker to overflow a stack buffer and potentially execute arbitrary code.

MitigationSince the vendor did not respond to the disclosure, implement compensating controls: restrict physical and shell access to the system, run the antivirus with minimum privileges, or consider alternative antivirus solutions. Monitor for any publicly available exploits targeting this vulnerability.

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 eScan Antivirus installation and version
    Run 'rpm -qa | grep escan' or 'dpkg -l | grep escan' depending on your package manager, or check for the presence of /opt/escan or /usr/lib/escan directories
    Affected if The installed version is exactly 7.0.32
  2. Locate the rtscanner binary
    Search for the rtscanner binary using 'find / -name rtscanner 2>/dev/null' or check common eScan installation paths like /opt/escan/
    Affected if The rtscanner binary exists and is from eScan version 7.0.32
  3. Verify the Watch List Handler configuration
    Check eScan configuration files for Watch List settings, typically found in /opt/escan/etc/ or /etc/escan/ directory
    Affected if A Watch List is configured with folder paths that the rtscanner monitors in real-time
  4. Confirm rtscanner service is active
    Check if the rtscanner service is running using 'ps aux | grep rtscanner' or 'systemctl status escan'
    Affected if The rtscanner service is actively running and processing watched folder paths

You are affected only if eScan Antivirus version 7.0.32 is installed with the rtscanner component active and a Watch List configured, as the buffer overflow occurs in the removeExtraSlashes function when processing watched folder paths.
