high Nessus Plugin ID 146968

Synopsis

The remote Debian host is missing a security update.

Description

A vulnerability was discovered in how p2p/p2p_pd.c in wpa_supplicant before 2.10 processes P2P (Wi-Fi Direct) provision discovery requests.
It could result in denial of service or other impact (potentially execution of arbitrary code), for an attacker within radio range.

For Debian 9 stretch, this problem has been fixed in version 2:2.4-1+deb9u9.

We recommend that you upgrade your wpa packages.
