Description Michael Kaplan 2020-03-06 14:31:57 UTC 
hostapd before 2.6, in EAP mode, makes calls to the rand() and random() standard library functions without any preceding srand() or srandom() call, which results in inappropriate use of deterministic values. This was fixed in conjunction with CVE-2016-10743.

Comment 1 Huzaifa S. Sidhpurwala 2020-03-27 06:44:21 UTC 
Analysis:

This issue is only triggered with WPS pin needs to be generated and there is no /dev/urandom device. Such a scenario should not be possible in a typical server configuration, and may be a case in case of IoT or embedded devices. Therefore marking Red Hat Products as not affected.
