Debian Stretch: DLA-2572-1 Moderate: wpa Buffer Overflow DoS Risk

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:
