Jouni Malinen discovered an input sanitization issue in the wpa_cli and hostapd_cli tools included in the wpa package. A remote wifi system within range could provide a crafted string triggering arbitrary code execution running with privileges of the affected wpa_cli or hostapd_cli process.

For the stable distribution (wheezy), this problem has been fixed in version 1.0-3+deb7u1. For the testing distribution (jessie), this problem will be fixed soon. For the unstable distribution (sid), this problem has been fixed in version 2.3-1. We recommend that you upgrade your wpa packages.
