samba vulnerabilities
==========================================================================

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

- Ubuntu 15.10
- Ubuntu 14.04 LTS
- Ubuntu 12.04 LTS

Summary:

Several security issues were fixed in Samba.

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

Details:

Jeremy Allison discovered that Samba incorrectly handled ACLs on symlink
paths. A remote attacker could use this issue to overwrite the ownership of
ACLs using symlinks. (CVE-2015-7560)

Garming Sam and Douglas Bagnall discovered that the Samba internal DNS
server incorrectly handled certain DNS TXT records. A remote attacker could
use this issue to cause Samba to crash, resulting in a denial of service,
or possibly obtain uninitialized memory contents. This issue only applied
to Ubuntu 14.04 LTS and Ubuntu 15.10. (CVE-2016-0771)

It was discovered that the Samba Web Administration Tool (SWAT) was
vulnerable to clickjacking and cross-site request forgery attacks. This
issue only affected Ubuntu 12.04 LTS. (CVE-2013-0213, CVE-2013-0214)

Update instructions:

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

Ubuntu 15.10:
samba 2:4.1.17+dfsg-4ubuntu3.3

Ubuntu 14.04 LTS:
samba 2:4.1.6+dfsg-1ubuntu2.14.04.13

Ubuntu 12.04 LTS:
samba 2:3.6.3-2ubuntu2.17
swat 2:3.6.3-2ubuntu2.17

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