GHSA-G3JF-H663-MQRX

Vulnerability from github – Published: 2022-10-18 12:00 – Updated: 2022-10-19 19:00

Details

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

Severity ?

7.3 (High)
