Security Bulletin

This security bulletin contains information about 2 vulnerabilities.

1) Information disclosure

EUVDB-ID: #VU20415

Risk: Low

CVSSv4.0: 2.3 [CVSS:4.0/AV:A/AC:L/AT:P/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2019-13377

CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor

Exploit availability: No

Description

The vulnerability allows a remote attacker to conduct time-based side-channel attacks on a targeted system.

The vulnerability exists due to insufficient security restrictions during the WPA3's Dragonfly handshake process when using Brainpool curves. A remote in radio range of the access point can observe timing differences and cache access patterns, conduct a side-channel attack and access sensitive information that could be used for full password recovery.



Mitigation

Install updates from vendor's repository.

Vulnerable software versions

Fedora: 7

hostapd: before 2.9-1.el7

2) NULL pointer dereference

EUVDB-ID: #VU31083

Risk: Medium

CVSSv4.0: 4.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2019-11555

CWE-ID: CWE-476 - NULL Pointer Dereference

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a NULL pointer dereference error in hostapd (EAP server) before 2.8 and wpa_supplicant (EAP peer) before 2.8 does not validate fragmentation reassembly state properly for a case where an unexpected fragment could be received. This could result in process termination due to a NULL pointer dereference (denial of service). This affects eap_server/eap_server_pwd.c and eap_peer/eap_pwd.c. A remote attacker can perform a denial of service (DoS) attack.

Mitigation

Install updates from vendor's repository.
