Package        : wpa
Version        : 2:2.4-1+deb9u8
CVE ID         : CVE-2021-0326


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.
