Amazon Linux AMI : freeradius (ALAS-2023-1699)

high Nessus Plugin ID 172188

Language:

Synopsis

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

Description

The version of freeradius installed on the remote host is prior to 2.2.6-7.17. It is, therefore, affected by a vulnerability as referenced in the ALAS-2023-1699 advisory.

 - In freeradius, when an EAP-SIM supplicant sends an unknown SIM option, the server will try to look that option up in the internal dictionaries. This lookup will fail, but the SIM code will not check for that failure. Instead, it will dereference a NULL pointer, and cause the server to crash. (CVE-2022-41860)

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.
