A vulnerability was found in how WPA code can be triggered to reconfigure WPA/WPA2/RSN keys (TK, GTK, or IGTK) by replaying a specific frame that is used to manage the keys. Such reinstallation of the encryption key can result in two different types of vulnerabilities: disabling replay protection and significantly reducing the security of encryption to the point of allowing frames to be decrypted or some parts of the keys to be determined by an attacker depending on which cipher is used.

Those issues are commonly known under the 'KRACK' appelation.
According to US-CERT, 'the impact of exploiting these vulnerabilities includes decryption, packet replay, TCP connection hijacking, HTTP content injection, and others.'

CVE-2017-13077

Reinstallation of the pairwise encryption key (PTK-TK) in the 4-way handshake.

CVE-2017-13078

Reinstallation of the group key (GTK) in the 4-way handshake.

CVE-2017-13079

Reinstallation of the integrity group key (IGTK) in the 4-way handshake.

CVE-2017-13080

Reinstallation of the group key (GTK) in the group key handshake.

CVE-2017-13081

Reinstallation of the integrity group key (IGTK) in the group key handshake.

CVE-2017-13082

Accepting a retransmitted Fast BSS Transition (FT) Reassociation Request and reinstalling the pairwise encryption key (PTK-TK) while processing it.

CVE-2017-13084

Reinstallation of the STK key in the PeerKey handshake.

CVE-2017-13086

reinstallation of the Tunneled Direct-Link Setup (TDLS) PeerKey (TPK) key in the TDLS handshake.

CVE-2017-13087

reinstallation of the group key (GTK) when processing a Wireless Network Management (WNM) Sleep Mode Response frame.

CVE-2017-13088

reinstallation of the integrity group key (IGTK) when processing a Wireless Network Management (WNM) Sleep Mode Response frame.

For Debian 7 'Wheezy', these problems have been fixed in version 1.0-3+deb7u5. Note that the latter two vulnerabilities (CVE-2017-13087 and CVE-2017-13088) were mistakenly marked as fixed in the changelog whereas they simply did not apply to the 1.0 version of the WPA source code, which doesn't implement WNM sleep mode responses.

We recommend that you upgrade your wpa packages.

This update for wpa_supplicant fixes the security issues :

  - Several vulnerabilities in standard conforming     implementations of the WPA2 protocol have been     discovered and published under the code name KRACK. This     update remedies those issues in a backwards compatible     manner, i.e. the updated wpa_supplicant can interface     properly with both vulnerable and patched     implementations of WPA2, but an attacker won't be able     to exploit the KRACK weaknesses in those connections     anymore even if the other party is still vulnerable.
