Miggo AIRoot Cause Analysis

The vulnerability stems from the insecure 777 permissions set on the temporary directory during live snapshots. The commit diff shows the vulnerable code in 'nova/virt/libvirt/driver.py' where 'chmod 777' was called via utils.execute. This function is directly responsible for configuring the directory permissions, and the patch replaces it with a secure alternative (0o701). The explicit use of 777 permissions in the original code matches the vulnerability description, making this function the clear root cause.
