"Similar to CVE-2016-10743 the host access point daemon, hostapd, in
EAP mode used a low quality pseudorandom number generator that leads
to insufficient entropy. The problem was resolved by using the
os_get_random function which provides cryptographically strong pseudo
random data.

For Debian 8 'Jessie', this problem has been fixed in version
2.3-1+deb8u10.

We recommend that you upgrade your wpa packages.

block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues.");
