CVE-2018-14526: | An issue was discovered in rsn_supp/wpa.c in
wpa_supplicant 2.0 | through 2.6. Under certain conditions, the
integrity of EAPOL-Key | messages is not checked, leading to a
decryption oracle. An attacker | within range of the Access Point and
client can abuse the | vulnerability to recover sensitive information.

For Debian 8 'Jessie', this problem has been fixed in version
2.3-1+deb8u6.

We recommend that you upgrade your wpa packages.

block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues.");
