17 Jan 2023 — 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. En freeradius, la función EAP-PWD Compute_password_element() filtra información sobre la contraseña, lo que permite a un atacante reducir sustancialmente el tamaño de un ataque de diccionario fuera de línea.

https://notcve.org/view.php?id=CVE-2022-41860
04 Jan 2023 — 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. En freeradius, cuando un solicitante de EAP-SIM envía una opción SIM desconocida, el servidor intentará buscar esa opción en los diccionarios internos. Esta búsqueda fallará, pero el código SIM no verificará ese error. • https://freeradius.org/security • CWE-476: NULL Pointer Dereference •

https://notcve.org/view.php?id=CVE-2022-41861
04 Jan 2023 — A flaw was found in freeradius. A malicious RADIUS client or home server can send a malformed abinary attribute which can cause the server to crash. It was discovered that FreeRADIUS incorrectly handled multiple EAP-pwd handshakes. An attacker could possibly use this issue to cause a denial of service. This issue only affected Ubuntu 18.04 LTS. • https://freeradius.org/security • CWE-20: Improper Input Validation CWE-400: Uncontrolled Resource Consumption •

24 May 2019 — It was discovered freeradius up to and including version 3.0.19 does not correctly configure logrotate, allowing a local attacker who already has control of the radiusd user to escalate his privileges to root, by tricking logrotate into writing a radiusd-writable file to a directory normally inaccessible by the radiusd user.
