Ubuntu 16.04 ESM / 18.04 ESM : Bind vulnerability (USN-6183-2)

high Nessus Plugin ID 178445

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 16.04 ESM / 18.04 ESM host has packages installed that are affected by a vulnerability as referenced in the USN-6183-2 advisory.

 - Every `named` instance configured to run as a recursive resolver maintains a cache database holding the responses to the queries it has recently sent to authoritative servers. The size limit for that cache database can be configured using the `max-cache-size` statement in the configuration file; it defaults to 90% of the total amount of memory available on the host. When the size of the cache reaches 7/8 of the configured limit, a cache-cleaning algorithm starts to remove expired and/or least-recently used RRsets from the cache, to keep memory use below the configured limit. It has been discovered that the effectiveness of the cache-cleaning algorithm used in `named` can be severely diminished by querying the resolver for specific RRsets in a certain order, effectively allowing the configured `max-cache-size` limit to be significantly exceeded. This issue affects BIND 9 versions 9.11.0 through 9.16.41, 9.18.0 through 9.18.15, 9.19.0 through 9.19.13, 9.11.3-S1 through 9.16.41-S1, and 9.18.11-S1 through 9.18.15-S1.
 (CVE-2023-2828)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution
