Kerentanan Improper Check for Dropped Privileges pada zsh, fedoraproject fedora +6 lainnya. Skor CVSS 3.1 7.8 (High) menurut NVD.

Deskripsi (NVD)

In Zsh before 5.8, attackers able to execute commands can regain privileges dropped by the --no-PRIVILEGED option. Zsh fails to overwrite the saved uid, so the original privileges can be restored by executing MODULE_PATH=/dir/with/module zmodload with a module that calls setuid().
