Azure Linux 3.0 Security Update: c-ares / fluent-bit / grpc / nodejs (CVE-2023-32067)

high Nessus Plugin ID 216086

Synopsis

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

Description

The version of c-ares / fluent-bit / grpc / nodejs 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-2023-32067 advisory.

 - c-ares is an asynchronous resolver library. c-ares is vulnerable to denial of service. If a target resolver sends a query, the attacker forges a malformed UDP packet with a length of 0 and returns them to the target resolver. The target resolver erroneously interprets the 0 length as a graceful shutdown of the connection. This issue has been patched in version 1.19.1. (CVE-2023-32067)

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.
