Azure Linux 3.0 Security Update: bind / dhcp (CVE-2024-1975)

high Nessus Plugin ID 215477

Synopsis

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

Description

The version of bind / dhcp 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-2024-1975 advisory.

 - If a server hosts a zone containing a KEY Resource Record, or a resolver DNSSEC-validates a KEY Resource Record from a DNSSEC-signed domain in cache, a client can exhaust resolver CPU resources by sending a stream of SIG(0) signed requests. This issue affects BIND 9 versions 9.0.0 through 9.11.37, 9.16.0 through 9.16.50, 9.18.0 through 9.18.27, 9.19.0 through 9.19.24, 9.9.3-S1 through 9.11.37-S1, 9.16.8-S1 through 9.16.49-S1, and 9.18.11-S1 through 9.18.27-S1. (CVE-2024-1975)

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