EulerOS 2.0 SP3 : freeradius (EulerOS-SA-2020-2133)

medium Nessus Plugin ID 140900

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

According to the versions of the freeradius package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

 - 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)

 - In FreeRADIUS 3.0 through 3.0.19, on average 1 in every 2048 EAP-pwd handshakes fails because the password element cannot be found within 10 iterations of the hunting and pecking loop. This leaks information that an attacker can use to recover the password of any user. This information leakage is similar to the 'Dragonblood' attack and CVE-2019-9494.(CVE-2019-13456)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected freeradius packages.
