When processing surfaces, the lifetime may outlive a persistent buffer leading to memory corruption and a potentially exploitable crash. This vulnerability affects Firefox < 81.

The remote Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4546-1 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, conduct cross-     site scripting (XSS) attacks, spoof the site displayed in the download dialog, or execute arbitrary code.

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.

The version of Firefox installed on the remote Windows host is prior to 81.0. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2020-42 advisory. Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The version of Firefox installed on the remote macOS or Mac OS X host is prior to 81.0. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2020-42 advisory. Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
