Debian DLA-1737-1 : pdns security update

high Nessus Plugin ID 123524

Language:

Synopsis

The remote Debian host is missing a security update.

Description

A vulnerability was found in PowerDNS Authoritative Server before 4.0.7 and before 4.1.7. An insufficient validation of data coming from the user when building a HTTP request from a DNS query in the HTTP Connector of the Remote backend, allowing a remote user to cause a denial of service by making the server connect to an invalid endpoint, or possibly information disclosure by making the server connect to an internal endpoint and somehow extracting meaningful information about the response.

Only installations using the pdns-backend-remote package are affected.

For Debian 8 'Jessie', this problem has been fixed in version 3.4.1-4+deb8u9.

We recommend that you upgrade your pdns packages.

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

Solution

Upgrade the affected packages.
