Amazon Linux 2 : freeradius (ALAS-2024-2611)

critical Nessus Plugin ID 205726

Language:

Synopsis

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

Description

The version of freeradius installed on the remote host is prior to 3.0.27-1. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2024-2611 advisory.

 RADIUS Protocol under RFC 2865 is susceptible to forgery attacks by a local attacker who can modify any valid Response (Access-Accept, Access-Reject, or Access-Challenge) to any other response using a chosen- prefix collision attack against MD5 Response Authenticator signature. (CVE-2024-3596)

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 freeradius' to update your system.
