Debian DLA-2572-1 : wpa security update

high Nessus Plugin ID 146665

Language:

Synopsis

The remote Debian host is missing a security update.

Description

An issue has been found in wpa, a set of tools to support WPA and WPA2 (IEEE 802.11i). Missing validation of data can result in a buffer over-write, which might lead to a DoS of the wpa_supplicant process or potentially arbitrary code execution.

On request, together with this upload support for WPA-EAP-SUITE-B(-192) has been enabled.

For Debian 9 stretch, this problem has been fixed in version 2:2.4-1+deb9u8.

We recommend that you upgrade your wpa packages.

For the detailed security status of wpa please refer to its security tracker page at: https://security-tracker.debian.org/tracker/wpa

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.
