Versions Affected : All versions prior to FreeNAS 11.2-U4

Description

A flaw was found in the way samba implemented an RPC endpoint emulating the Windows registry service API.

An unprivileged attacker could use this flaw to create a new registry hive file anywhere they have unix permissions which could lead to creation of a new file in the Samba share. Versions before 4.8.11, 4.9.6 and 4.10.2 are vulnerable.

Workaround

No workaround is available, but dynamically linked binaries are not affected.
