Rocky Linux 9 : c-ares (RLSA-2023:3559)

high Nessus Plugin ID 177262

Synopsis

The remote Rocky Linux host is missing a security update.

Description

The remote Rocky Linux 9 host has packages installed that are affected by a vulnerability as referenced in the RLSA-2023:3559 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.
