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 malicious SCP server can send unexpected paths that could make the client application override local files outside of working directory. This could be misused to create malicious executable or configuration files and make the user execute them under specific consequences. This is the same issue as in OpenSSH, tracked as CVE-2019-6111.

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 · high confidence

A path traversal vulnerability in the SCP client allows a malicious server to send unexpected path information that tricks the client into writing files outside the intended working directory, potentially overwriting system files, configurations, or creating malicious executables.

MitigationImplement strict path validation on the client side to reject any file paths containing '..' sequences or paths that resolve outside the intended working directory, ensuring all server-sent paths are validated before any file operations occur.

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. Identify installed libssh version
    Run 'rpm -qa | grep libssh' or 'ssh -V' to determine the libssh library version installed on the system
    Affected if The installed version is less than 0.11.4
  2. Verify Red Hat Enterprise Linux version
    Run 'cat /etc/redhat-release' to check the RHEL version
    Affected if The version is 8.0, 9.0, or 10.0 exactly
  3. Check if Red Hat Openshift Container Platform 4.0 is in use
    Run 'oc version' or check cluster configuration to determine if OCP 4.0 is deployed
    Affected if Openshift Container Platform version 4.0 is installed
  4. Determine if SCP client functionality is actively used
    Review system logs or configuration for SCP file transfer operations, or check which SSH client binaries are in use
    Affected if The system uses SCP client to receive files from remote servers

You are affected if your environment uses libssh version below 0.11.4, or runs RHEL 8.0/9.0/10.0, OCP 4.0, or Red Hat Hardened Images, and utilizes SCP client functionality to transfer files from remote servers.

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.

dbcve · scoped
Upgrade available Upgrade to 0.11.4 or later
Fixed in 0.11.4
Interim mitigation

Implement strict path validation on the client side to reject any file paths containing '..' sequences or paths that resolve outside the intended working directory, ensuring all server-sent paths are validated before any file operations occur.

Recommended fix High confidence

libssh version 0.11.4 or later

  1. 1. Identify the current libssh version installed on the system using: rpm -q libssh or dpkg -l libssh4
  2. 2. For Enterprise Linux systems (RHEL 8.0, 9.0, 10.0), update libssh using: sudo dnf update libssh
  3. 3. For Debian/Ubuntu-based systems, update using: sudo apt update && sudo apt install libssh-4
  4. 4. For Hardened Images or OpenShift Container Platform 4.0, update the underlying RHEL OS which contains the libssh package
  5. 5. After updating, verify the new version is installed: rpm -q libssh (should show version 0.11.4 or later)
  6. 6. Restart any services that use libssh (such as SSH clients or applications that link against libssh) to ensure the updated library is loaded
  7. 7. Test SCP functionality to ensure the client still works correctly after the update
Caveat Minimal risk - this is a client-side security fix; updating to 0.11.4 should not break existing functionality
