Detail

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 19.04

Summary:

Samba would allow unintended access to files over the network.

Software Description: - samba: SMB/CIFS file, print, and login server for Unix

Details:

Stefan Metzmacher discovered that the Samba SMB server did not properly prevent clients from escaping outside the share root directory in some situations. An attacker could use this to gain access to files outside of the Samba share, where allowed by the permissions of the underlying filesystem.

Update instructions:

The problem can be corrected by updating your system to the following package versions:

Ubuntu 19.04:
samba 2:4.10.0+dfsg-0ubuntu2.4

In general, a standard system update will make all the necessary changes.
