Ubuntu Security Notice USN-4167-1
Posted Oct 29, 2019
Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 4167-1 - 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. Simon Fonteneau and Bjoern Baumbach discovered that Samba incorrectly handled the check password script. This issue could possibly bypass custom password complexity checks, contrary to expectations. This issue only affected Ubuntu 18.04 LTS, Ubuntu 19.04, and Ubuntu 19.10. Various other issues were also addressed.

Summary:

Several security issues were fixed in Samba.

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

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)

Simon Fonteneau and Björn Baumbach discovered that Samba incorrectly
handled the check password script. This issue could possibly bypass custom
password complexity checks, contrary to expectations. This issue only
affected Ubuntu 18.04 LTS, Ubuntu 19.04, and Ubuntu 19.10. (CVE-2019-14833)

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.
(CVE-2019-14847)

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

Ubuntu 19.10:
libsmbclient 2:4.10.7+dfsg-0ubuntu2.2
