Amazon Linux 2 : c-ares (ALAS-2024-2429)

low Nessus Plugin ID 189323

Language:

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of c-ares installed on the remote host is prior to 1.10.0-3. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2024-2429 advisory.

 When cross-compiling c-ares and using the autotools build system, CARES_RANDOM_FILE will not be set, as seen when cross compiling aarch64 android. This will downgrade to using rand() as a fallback which could allow an attacker to take advantage of the lack of entropy by not using a CSPRNG. (CVE-2023-31124)

Tenable has extracted the preceding description block directly from the tested product security advisory.

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.
