CVE-2013-2007
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 · uneditedThe qemu guest agent in Qemu 1.4.1 and earlier, as used by Xen, when started in daemon mode, uses weak permissions for certain files, which allows local users to read and write to these 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 confidenceThe qemu guest agent in Qemu 1.4.1 and earlier, as used by Xen, creates files with weak permissions when started in daemon mode. This allows local users to read and potentially modify these files, leading to information disclosure or privilege escalation.

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.
-
Identify QEMU installation and versionRun 'qemu-img --version' or 'qemu-system-x86_64 --version' to determine the installed QEMU versionAffected if The version is 1.4.1 or earlier
-
Locate qemu guest agentCheck if qemu-guest-agent daemon is present on the system using 'which qemu-ga' or 'ps aux | grep qemu-ga'Affected if The qemu-guest-agent daemon is installed and running
-
Verify daemon mode operationInspect the qemu-guest-agent process and its configuration to determine if it was started in daemon mode (check init scripts, systemd service files, or process arguments)Affected if The guest agent is running as a daemon (not in foreground or interactive mode)
-
Inspect file permissionsLocate qemu guest agent files (typically socket files in /var/lib/qemu or /var/run, and log/state files) and check their permissions using 'ls -la'Affected if Files or sockets are owned by root but readable/writable by other users (e.g., permissions like 0666 or 0777, or group/world-readable)
-
Compare against vulnerable configurationIf the agent runs in daemon mode and files are world-readable/writable, the system is vulnerable regardless of versionAffected if Daemon mode is enabled AND weak file permissions (world-readable or group-readable) exist on agent files/sockets
A system is affected if it runs QEMU version 1.4.1 or earlier with the qemu-guest-agent running in daemon mode, and if agent-related files or sockets have overly permissive access controls.
Generated from the published advisory. Verify against your own configuration.
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 dataUpgrade Qemu to a version newer than 1.4.1, or manually enforce restrictive permissions on qemu guest agent files and sockets in daemon mode.
