Synopsis

The remote Ubuntu host is missing a security-related patch.

Description

USN-4474-1 fixed vulnerabilities in Firefox. The update introduced various minor regressions. This update fixes the problem. We apologize for the inconvenience.

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, trick the user in to installing a malicious extension, spoof the URL bar, leak sensitive information between origins, or execute arbitrary code.
(CVE-2020-15664, CVE-2020-15665, CVE-2020-15666, CVE-2020-15670) It was discovered that NSS incorrectly handled certain signatures. An attacker could possibly use this issue to expose sensitive information. (CVE-2020-12400, CVE-2020-12401, CVE-2020-6829) A data race was discovered when importing certificate information in to the trust store. An attacker could potentially exploit this to cause an unspecified impact. (CVE-2020-15668).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected firefox package.
