Oracle Linux 9 : c-ares (ELSA-2023-3559)

high Nessus Plugin ID 177280

Language:

Synopsis

The remote Oracle Linux host is missing a security update.

Description

The remote Oracle Linux 9 host has packages installed that are affected by a vulnerability as referenced in the ELSA-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 c-ares and / or c-ares-devel packages.
