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
Race condition in the mounting process in vmware-mount in VMware Workstation 7.x before 7.1.2 build 301548 on Linux, VMware Player 3.1.x before 3.1.2 build 301548 on Linux, VMware Server 2.0.2 on Linux, and VMware Fusion 3.1.x before 3.1.2 build 332101 allows host OS users to gain privileges via vectors involving temporary files.

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 race condition exists in the vmware-mount utility across multiple VMware products on Linux where temporary files are created insecurely during the mounting process. An attacker with local host OS access can exploit this race condition to perform a privilege escalation attack by manipulating the temporary files before they are used, potentially gaining elevated privileges on the host system.

MitigationUpdate affected VMware products to version 7.1.2 build 301548 (Workstation), 3.1.2 build 301548 (Player/Fusion), or later. For VMware Server 2.0.2, consider migrating to a supported product or implementing additional access controls on the vmware-mount utility.

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 vmware-mount utility is installed
    Locate the vmware-mount binary on the system. Common paths include /usr/bin/vmware-mount, /usr/local/bin/vmware-mount, or search using 'which vmware-mount' or 'find / -name vmware-mount 2>/dev/null'. Also check for vmware-mount in the VMware product installation directory.
    Affected if vmware-mount utility is found on the system, indicating an affected VMware product may be installed.
  2. Identify the installed VMware product
    Determine which VMware product is installed by checking for product-specific directories or binaries. Common locations: VMware Workstation (/usr/lib/vmware, /opt/vmware), VMware Player (/usr/lib/vmware, /opt/vmware), VMware Server (/usr/lib/vmware/server), VMware Fusion (typically /Applications/VMware Fusion.app on macOS but this CVE is Linux-focused). Check /usr/lib/vmware-*/common/manifest or look for product-specific files.
    Affected if A VMware product is installed and matches the affected product list.
  3. Determine the installed version number
    Run the vmware-mount utility with version flag: 'vmware-mount --version' or check the product-specific version. For VMware Workstation, check 'vmware -v' or look in /usr/lib/vmware/etc/versions or the installer logs. For VMware Player, check 'vmplayer --version'. For VMware Server, check 'vmware-serverd --version' or check /usr/lib/vmware/server/config.
    Affected if The installed version matches exactly: Workstation 7.0, 7.0.1, 7.1, 7.1.1, or 7.1.2; Player 3.1, 3.1.1, or 3.1.2; Server 2.0.2; Fusion 3.1, 3.1.1, or 3.1.2.
  4. Verify the vulnerable temp file behavior exists
    While the CVE exploits a race condition during actual use, you can verify the vmware-mount utility is present and executable by attempting 'vmware-mount -h' or checking file permissions. The vulnerability manifests when mounting operations create temporary files in predictable locations with insecure permissions.
    Affected if vmware-mount is executable and present on a Linux system running an affected version, making it potentially exploitable.

A user is affected if they have any of the listed VMware product versions (Workstation 7.0-7.1.2, Player 3.1-3.1.2, Server 2.0.2, Fusion 3.1-3.1.2) installed on Linux and the vmware-mount utility is present and accessible on the system.
