CVE-2019-3880: Debian Linux

Medium severity, CVSS 5.4. EPSS: 3.2% chance of exploitation in the next 30 days.

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.
