According to the versions of the wpa_supplicant package installed, the EulerOS 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.

When hostapd is used to operate an access point with SAE (Simultaneous Authentication of Equals; also known as WPA3-Personal), an invalid authentication sequence could result in the hostapd process terminating due to a NULL pointer dereference when processing SAE confirm message. This was caused by missing state validation steps when processing the SAE confirm message in hostapd/AP mode.

See https://w1.fi/security/2019-3/sae-confirm-missing-state-validation.txt for a detailed description of the bug. Impact : All hostapd versions with SAE support (CONFIG_SAE=y in the build configuration and SAE being enabled in the runtime configuration).

An update of the wpa_supplicant package has been released.
