Udisks: missing authorization check allows unprivileged users to back up luks headers via udisks d-bus api
Résumé
Udisks: missing authorization check allows unprivileged users to back up luks headers via udisks d-bus api
Description d'origine
La description telle que publiée par la source (souvent en anglais).
A flaw was found in the udisks storage management daemon that allows unprivileged users to back up LUKS encryption headers without authorization. The issue occurs because a privileged D-Bus method responsible for exporting encryption metadata does not perform a policy check. As a result, sensitive cryptographic metadata can be read and written to attacker-controlled locations. This weakens the confidentiality guarantees of encrypted storage volumes.
