high Nessus Plugin ID 171951

Language:

Synopsis

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

Description

The remote Ubuntu 18.04 LTS / 20.04 LTS / 22.04 LTS / 22.10 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5892-1 advisory.

 - A vulnerability found in nss. By this security vulnerability, nss client auth crash without a user certificate in the database and this can lead us to a segmentation fault or crash. (CVE-2022-3479)

 - An attacker could construct a PKCS 12 cert bundle in such a way that could allow for arbitrary memory writes via PKCS 12 Safe Bag attributes being mishandled. (CVE-2023-0767)

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 libnss3, libnss3-dev and / or libnss3-tools packages.
