Description

The remote host is affected by the vulnerability described in GLSA-202401-02 (c-ares: Multiple Vulnerabilities)

- A flaw was found in c-ares library, where a missing input validation check of host names returned by DNS (Domain Name Servers) can lead to output of wrong hostnames which might potentially lead to Domain Hijacking. The highest threat from this vulnerability is to confidentiality and integrity as well as system availability. (CVE-2021-3672)

- Node.js before 16.6.0, 14.17.4, and 12.22.4 is vulnerable to a use after free attack where an attacker might be able to exploit the memory corruption, to change process behavior. (CVE-2021-22930)

- Node.js before 16.6.0, 14.17.4, and 12.22.4 is vulnerable to Remote Code Execution, XSS, Application crashes due to missing input validation of host names returned by Domain Name Servers in Node.js dns library which can lead to output of wrong hostnames (leading to Domain Hijacking) and injection vulnerabilities in applications using the library. (CVE-2021-22931)

- If the Node.js https API was used incorrectly and undefined was in passed for the rejectUnauthorized parameter, no error was returned and connections to servers with an expired certificate would have been accepted. (CVE-2021-22939)

- Node.js before 16.6.1, 14.17.5, and 12.22.5 is vulnerable to a use after free attack where an attacker might be able to exploit the memory corruption, to change process behavior. (CVE-2021-22940)

- A flaw was found in the c-ares package. The ares_set_sortlist is missing checks about the validity of the input string, which allows a possible arbitrary length stack overflow. This issue may cause a denial of service or a limited impact on confidentiality and integrity. (CVE-2022-4904)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

All c-ares users should upgrade to the latest version:

# emerge --sync # emerge --ask --oneshot --verbose >=net-dns/c-ares-1.19.0
