Accountsservice: accountsservice: arbitrary file read via seticonfile for systemd-homed users

Title source: cna

Description

A flaw was found in accountsservice. The systemd-homed code path for SetIconFile opens a user-supplied filename as root without the validation and privilege drop performed by the classic handler. A local attacker with a systemd-homed-managed account can read arbitrary files accessible to the accounts-daemon process.
