Description

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.

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