Summary

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. 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. Red Hat severity: Moderate — CVSS 5.5 (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N).

Weakness: CWE-269. Red Hat does not currently list a fixing RHSA for this CVE.

Affected products named by the advisory: Red Hat Enterprise Linux 10; Red Hat Enterprise Linux 7; Red Hat Enterprise Linux 8; Red Hat Enterprise Linux 9; and 1 more.
