Details

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.
(CVE-2019-10218)

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)
