DLA 3342-1: freeradius security update

Debian LTS Advisory DLA-3342-1 Markus Koschany
February 24, 2023

Package : freeradius
Version : 3.0.17+dfsg-1.1+deb10u2
CVE ID : CVE-2022-41859 CVE-2022-41860 CVE-2022-41861

Several flaws were found in freeradius, a high-performance and highly
configurable RADIUS server.


In freeradius, the EAP-PWD function compute_password_element() leaks
information about the password which allows an attacker to substantially
reduce the size of an offline dictionary attack.


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.


A malicious RADIUS client or home server can send a malformed attribute
which can cause the server to crash.

For Debian 10 buster, these problems have been fixed in version

We recommend that you upgrade your freeradius packages.
