EulerOS 2.0 SP10 : c-ares (EulerOS-SA-2023-2374)

high Nessus Plugin ID 178392

Synopsis

The remote EulerOS host is missing a security update.

Description

According to the versions of the c-ares package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

 - 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 Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected c-ares packages.
