Azure Linux 3.0 Security Update: bind (CVE-2023-4408)

high Nessus Plugin ID 215673

Synopsis

The remote Azure Linux host is missing one or more security updates.

Description

The version of bind installed on the remote Azure Linux 3.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2023-4408 advisory.

 - The DNS message parsing code in `named` includes a section whose computational complexity is overly high.
 It does not cause problems for typical DNS traffic, but crafted queries and responses May cause excessive CPU load on the affected `named` instance by exploiting this flaw. This issue affects both authoritative servers and recursive resolvers. This issue affects BIND 9 versions 9.0.0 through 9.16.45, 9.18.0 through 9.18.21, 9.19.0 through 9.19.19, 9.9.3-S1 through 9.11.37-S1, 9.16.8-S1 through 9.16.45-S1, and 9.18.11-S1 through 9.18.21-S1. (CVE-2023-4408)

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

Solution

Update the affected packages.
