Debian DLA-1733-1 : wpa security update

high Nessus Plugin ID 123470

Language:

Synopsis

The remote Debian host is missing a security update.

Description

It was found that the fallback mechanism for generating a WPS pin in hostapd, an IEEE 802.11 AP and IEEE 802.1X/WPA/WPA2/EAP Authenticator, used a low quality pseudorandom number generator. This was resolved by using only the high quality os_get_random function.

For Debian 8 'Jessie', this problem has been fixed in version 2.3-1+deb8u7.

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.

Solution

Upgrade the affected packages.
