EulerOS 2.0 SP8 : freeradius (EulerOS-SA-2020-1847)

high Nessus Plugin ID 139950

Synopsis

The remote EulerOS host is missing a security update.

Description

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

- 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)

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 package.
