medium Nessus Plugin ID 103319

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

USN-3346-1 fixed vulnerabilities in Bind. The fix for CVE-2017-3142 introduced a regression in the ability to receive an AXFR or IXFR in the case where TSIG is used and not every message is signed. This update fixes the problem.

In addition, this update adds the new root zone key signing key (KSK).

Clement Berthaux discovered that Bind did not correctly check TSIG authentication for zone update requests. An attacker could use this to improperly perform zone updates. (CVE-2017-3143)

Clement Berthaux discovered that Bind did not correctly check TSIG authentication for zone transfer requests. An attacker could use this to improperly transfer entire zones.
(CVE-2017-3142).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected packages.
