CVE-2014-0239

Publication date 28 May 2014

Last updated 24 July 2024

Ubuntu priority

Medium

Why this priority?

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.
