The remote Redhat Enterprise Linux 8 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2020:3557 advisory.
Mozilla Firefox is an open-source web browser, designed for standards compliance, performance, and portability.
This update upgrades Firefox to version 78.2.0 ESR.
Security Fix(es):
* Mozilla: Attacker-induced prompt for extension installation (CVE-2020-15664)
* Mozilla: Use-After-Free when aborting an operation (CVE-2020-15669)
* Mozilla: Integer overflow in nsJPEGEncoder::emptyOutputBuffer (CVE-2020-12422)
* Mozilla: X-Frame-Options bypass using object or embed tags (CVE-2020-15648)
* Mozilla: Bypassing iframe sandbox when allowing popups (CVE-2020-15653)
* Mozilla: Type confusion for special arguments in IonMonkey (CVE-2020-15656)
* Mozilla: WebRTC permission prompt could have been bypassed by a compromised content process (CVE-2020-12424)
* Mozilla: Out of bound read in Date.parse() (CVE-2020-12425)
* Mozilla: Custom cursor can overlay user interface (CVE-2020-15654)
* Mozilla: Overriding file type when saving to disk (CVE-2020-15658)
For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
