EulerOS Virtualization for ARM 64 18.104.22.168 : wpa_supplicant (EulerOS-SA-2019-1945)
Medium Nessus Plugin ID 128948
SynopsisThe remote EulerOS Virtualization for ARM 64 host is missing multiple security updates.
DescriptionAccording to the versions of the wpa_supplicant package installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities :
- The implementations of SAE in hostapd and wpa_supplicant are vulnerable to side channel attacks as a result of observable timing differences and cache access patterns. An attacker may be able to gain leaked information from a side channel attack that can be used for full password recovery. Both hostapd with SAE support and wpa_supplicant with SAE support prior to and including version 2.7 are affected.(CVE-2019-9494)
- An invalid authentication sequence could result in the hostapd process terminating due to missing state validation steps when processing the SAE confirm message when in hostapd/AP mode. All version of hostapd with SAE support are vulnerable. An attacker may force the hostapd process to terminate, performing a denial of service attack. Both hostapd with SAE support and wpa_supplicant with SAE support prior to and including version 2.7 are affected.(CVE-2019-9496)
Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
SolutionUpdate the affected wpa_supplicant packages.
