Updated freeradius packages fix security vulnerabilities

Publication date: 05 Jan 2020
Type: security
Affected Mageia releases : 7
CVE: CVE-2019-10143 , CVE-2019-13456 , CVE-2019-17185


Updated freeradius packages fix security vulnerabilities:

It was discovered freeradius 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 (CVE-2019-10143).

An information leak was discovered in the implementation of EAP-pwd in
freeradius. An attacker could initiate several EAP-pwd handshakes to leak
information, which can then be used to recover the user's WiFi password by
performing dictionary and brute-force attacks (CVE-2019-13456).
