Amazon Linux AMI : c-ares (ALAS-2023-1780)

high Nessus Plugin ID 178499

Synopsis

The remote Amazon Linux AMI host is missing a security update.

Description

The version of c-ares installed on the remote host is prior to 1.17.2-1.10. It is, therefore, affected by a vulnerability as referenced in the ALAS-2023-1780 advisory.

- 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 this issue but has instead relied only on the application's self-reported version number.

Solution

Run 'yum update c-ares' to update your system.
