Detailsinfo

A vulnerability has been found in Google Drive for Desktop 64.0 on macOS (Cloud Software) and classified as critical. Affected by this vulnerability is an unknown functionality of the file /Applications/Google\ Drive.app/Contents/MacOS of the component Installer. The manipulation with an unknown input leads to a access control vulnerability. The CWE definition for the vulnerability is CWE-264. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

An attacker can pre-create the `/Applications/Google\ Drive.app/Contents/MacOS` directory which is expected to be owned by root to be owned by a non-root user. When the Drive for Desktop installer is run for the first time, it will place a binary in that directory with execute permissions and set its setuid bit. Since the attacker owns the directory, the attacker can replace the binary with a symlink, causing the installer to set the setuid bit on the symlink. When the symlink is executed, it will run with root permissions. We recommend upgrading past version 64.0
