Ubuntu 18.04 LTS / 20.04 LTS : Firefox vulnerabilities (USN-5131-1)

critical Nessus Plugin ID 154883

Language:

Synopsis

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

Description

The remote Ubuntu 18.04 LTS / 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5131-1 advisory.

 Multiple security issues were discovered in Firefox. If a user were tricked into opening a specially crafted website, an attacker could potentially exploit these to cause a denial of service, bypass security restrictions, spoof the browser UI, confuse the user, conduct phishing attacks, or execute arbitrary code.
 (CVE-2021-38503, CVE-2021-38504, CVE-2021-38506, CVE-2021-38507, CVE-2021-38508, CVE-2021-38509)

 It was discovered that the 'Copy Image Link' context menu action would copy the final image URL after redirects. If a user were tricked into copying and pasting a link for an embedded image that triggered authentication flows back to the page, an attacker could potentially exploit this to steal authentication tokens.

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.
