high Nessus Plugin ID 146736

Language:

Synopsis

The remote Debian host is missing a security update.

Description

It was discovered that there was a buffer overflow attack in the bind9 DNS server caused by an issue in the GSSAPI ('Generic Security Services') security policy negotiation.

For Debian 9 'Stretch', this problem has been fixed in version 1:9.10.3.dfsg.P4-12.3+deb9u8.

We recommend that you upgrade your bind9 packages.

For the detailed security status of bind9 please refer to its security tracker page at: https://security-tracker.debian.org/tracker/bind9

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.
