  script_tag(name:"insight", value:"Several flaws were found in freeradius, a high-performance and highly configurable RADIUS server.

CVE-2022-41859

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.

CVE-2022-41860

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-2022-41861

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 3.0.17+dfsg-1.1+deb10u2.

We recommend that you upgrade your freeradius packages.

For the detailed security status of freeradius please refer to its security tracker page at: [link moved to references]
