Security Bulletin
This security bulletin contains information about 6 vulnerabilities.
1) Key management errors
EUVDB-ID: #VU8838
Risk: High
CVSSv4.0: 7.4 [CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/U:Amber]
CVE-ID: CVE-2017-13078
CWE-ID:
CWE-320 - Key Management Errors
Exploit availability: No
DescriptionThe vulnerability allows an adjacent attacker to force a supplicant to reinstall a previously used group key.
The weakness exists in the processing of the 802.11i 4-way handshake messages of the WPA and WPA2 protocols due to ambiguities in the processing of associated protocol messages. An adjacent attacker can use man-in-the-middle techniques to retransmit previously used message exchanges between supplicant and authenticator.
Update the affected packages.

5) Key management errors
EUVDB-ID: #VU8846
Risk: High
CVSSv4.0: 7.4 [CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/U:Amber]
CVE-ID: CVE-2017-13087
CWE-ID:
CWE-320 - Key Management Errors
Exploit availability: No
DescriptionThe vulnerability allows an adjacent attacker to force a supplicant that is compliant with the 802.11v standard to reinstall a previously used group key.
The weakness exists in the processing of the 802.11v (Wireless Network Management) Sleep Mode Response frames due to ambiguities in the processing of associated protocol messages. An adjacent attacker can passively eavesdrop and retransmit previously used WNM Sleep Mode Response frames.
Update the affected packages.
