Package : samba
Version : 2:4.2.14+dfsg-0+deb8u11
CVE ID : CVE-2018-14629 CVE-2018-16851

Several vulnerabilities have been discovered in Samba, a SMB/CIFS file,
print, and login server for Unix. The Common Vulnerabilities and
Exposures project identifies the following issues:

CVE-2018-14629

Florian Stuelpner discovered that Samba is vulnerable to
infinite query recursion caused by CNAME loops, resulting in
denial of service.

CVE-2018-16851

Garming Sam of the Samba Team and Catalyst discovered a NULL pointer
dereference vulnerability in the Samba AD DC LDAP server allowing a
user able to read more than 256MB of LDAP entries to crash the Samba
AD DC&#x27;s LDAP server.

For Debian 8 "Jessie", these problems have been fixed in version
2:4.2.14+dfsg-0+deb8u11.

We recommend that you upgrade your samba packages.
