Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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)

Solution

Update the c-ares-1.13.0 library and its related packages to version 1.13.0+e1 or later.
