CVE-2014-0239  (opens in a new tab)
CWE-20  (opens in a new tab)

How to fix?

Upgrade Debian:10 samba to version 2:4.1.8+dfsg-1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream samba package and not the samba package as distributed by Debian. See How to fix? for Debian:10 relevant fixed versions and status.

The internal DNS server in Samba 4.x before 4.0.18 does not check the QR field in the header section of an incoming DNS message before sending a response, which allows remote attackers to cause a denial of service (CPU and bandwidth consumption) via a forged response packet that triggers a communication loop, a related issue to CVE-1999-0103.
