Ubuntu 20.04 LTS / 22.04 LTS / 24.04 LTS / 24.10 : wpa_supplicant and hostapd vulnerabilities (USN-7317-1)

critical Nessus Plugin ID 218383

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 20.04 LTS / 22.04 LTS / 24.04 LTS / 24.10 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-7317-1 advisory.

 George Chatzisofroniou and Panayiotis Kotzanikolaou discovered that wpa_supplicant and hostapd reused encryption elements in the PKEX protocol. An attacker could possibly use this issue to impersonate a wireless access point, and obtain sensitive information. (CVE-2022-37660)

 Daniel De Almeida Braga, Mohamed Sabt, and Pierre-Alain Fouque discovered that wpa_supplicant and hostapd were vulnerable to side channel attacks due to the cache access patterns. An attacker could possibly use this issue to obtain sensitive information. This issue only affected Ubuntu 20.04 LTS. (CVE-2022-23303, CVE-2022-23304)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
