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.

Statement

Red Hat Enterprise Linux is not affected. The accountsservice versions shipped in RHEL do not include the systemd-homed SetIconFile code path introduced in later upstream releases.
