Language:

Synopsis

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

Description

The remote Ubuntu 16.04 LTS / 18.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4323-1 advisory.

 Multiple security issues were discovered in Firefox. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit these to cause a denial of service, obtain sensitive information, or execute arbitrary code. (CVE-2020-6821, CVE-2020-6822, CVE-2020-6824, CVE-2020-6825, CVE-2020-6826)

 It was discovered that extensions could obtain auth codes from OAuth login flows in some circumstances. If a user were tricked in to installing a specially crafted extension, an attacker could potentially exploit this to obtain access to the user's account. (CVE-2020-6823)

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
