Amazon Linux 2 Security Advisory: ALAS-2020-1515
Advisory Release Date: 2020-10-22 17:34 Pacific
Advisory Updated Date: 2020-10-22 22:36 Pacific
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)
In FreeRADIUS 3.0.x before 3.0.20, the EAP-pwd module used a global OpenSSL BN_CTX instance to handle all handshakes. This mean multiple threads use the same BN_CTX instance concurrently, resulting in crashes when concurrent EAP-pwd handshakes are initiated. This can be abused by an adversary as a Denial-of-Service (DoS) attack. (CVE-2019-17185)
