Debian DLA-3342-1 : freeradius - LTS security update
high Nessus Plugin ID 171904
Language:
Synopsis
The remote Debian host is missing one or more security-related updates.Description
The remote Debian 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-3342 advisory.- 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-2022-41859)
- 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)
- 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. (CVE-2022-41861)
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
Solution
Upgrade the freeradius packages.For Debian 10 buster, these problems have been fixed in version 3.0.17+dfsg-1.1+deb10u2.
