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
w_export.c in XWine 1.0.1 on Debian GNU/Linux sets insecure permissions (0666) for /etc/wine/config, which might allow local users to execute arbitrary commands or cause a denial of service by modifying the file.

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

The w_export.c source file in XWine 1.0.1 creates the /etc/wine/config configuration file with overly permissive 0666 mode (world-readable and world-writable), allowing any local user to modify this sensitive configuration file and potentially execute arbitrary commands or cause denial of service.

MitigationRestrict permissions on /etc/wine/config to owner-only (0600) or owner-read/group-read (0640), and modify w_export.c to create the file with secure default permissions using umask or explicit chmod calls.

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. Verify XWine 1.0.1 installation
    Run 'rpm -q xwine' or 'dpkg -l xwine' or check your package manager for xwine version 1.0.1
    Affected if Xwine version 1.0.1 is installed
  2. Locate the configuration file
    Check if /etc/wine/config exists using 'ls -la /etc/wine/config'
    Affected if The file /etc/wine/config exists on the system
  3. Inspect file permissions
    Run 'stat -c %a /etc/wine/config' or 'ls -la /etc/wine/config' to view the octal permissions
    Affected if Permissions are 0666 (world-readable and world-writable) or any mode that allows write access by non-owners (such as 0664, 0660, or 0667)
  4. Verify owner and group ownership
    Run 'stat -c '%U:%G' /etc/wine/config' to see file owner and group
    Affected if The file is owned by root but permissions allow write access by other users (world-writable or group-writable to a group containing non-privileged users)

If XWine 1.0.1 is installed and /etc/wine/config exists with permissions that allow write access by non-privileged users (such as 0666), the system is vulnerable to local privilege escalation through configuration file modification.

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 data
Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Restrict permissions on /etc/wine/config to owner-only (0600) or owner-read/group-read (0640), and modify w_export.c to create the file with secure default permissions using umask or explicit chmod calls.
