The remote Ubuntu 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6710-1 advisory.

    Manfred Paul discovered that Firefox did not properly perform bounds checking during range analysis,     leading to an out-of-bounds write vulnerability. A attacker could use this to cause a denial of service,

    or execute arbitrary code. (CVE-2024-29943)

    Manfred Paul discovered that Firefox incorrectly handled MessageManager

    listeners under certain circumstances. An attacker who was able to inject

    an event handler into a privileged object may have been able to execute

    arbitrary code. (CVE-2024-29944)

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.
