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

- Ubuntu 14.04 ESM - Ubuntu 12.04 ESM


Several security issues were fixed in Samba.

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


USN-4167-1 fixed several vulnerabilities in Samba. This update provides the corresponding update for Ubuntu 12.04 ESM and Ubuntu 14.04 ESM.

Original advisory details:

Michael Hanselmann discovered that the Samba client code incorrectly
handled path separators. If a user were tricked into connecting to a
malicious server, a remote attacker could use this issue to cause the
client to access local pathnames instead of network pathnames.

Adam Xu discovered that Samba incorrectly handled the dirsync LDAP control.
A remote attacker with "get changes" permissions could possibly use this
issue to cause Samba to crash, resulting in a denial of service. This issue
only affected Ubuntu 14.04 ESM. (CVE-2019-14847)

Update instructions:

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

Ubuntu 14.04 ESM:
libsmbclient 2:4.3.11+dfsg-0ubuntu0.14.04.20+esm3
samba 2:4.3.11+dfsg-0ubuntu0.14.04.20+esm3

Ubuntu 12.04 ESM:
libsmbclient 2:3.6.25-0ubuntu0.12.04.19
samba 2:3.6.25-0ubuntu0.12.04.19

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