Package : freeradius Version : 3.0.21+dfsg-2.2+deb11u2 CVE ID : CVE-2022-41859 CVE-2022-41860 CVE-2022-41861
Several security vulnerabilities have been discovered in freeradius, a highly configurable RADIUS server.
CVE-2022-41859
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
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 abinary attribute which can cause the server to crash. This crash is not exploitable by end users. Only systems which are in the RADIUS circle of trust can send these malformed attributes to a server.
For Debian 11 bullseye, these problems have been fixed in version 3.0.21+dfsg-2.2+deb11u2.
We recommend that you upgrade your freeradius packages.
