The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the fb9ba490-5cc4-11ec-aac7-3065ec8fd3ec advisory.
Use after free in V8 in Google Chrome prior to 96.0.4664.110 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. (CVE-2021-4102)
Insufficient data validation in Mojo in Google Chrome prior to 96.0.4664.110 allowed a remote attacker who had compromised the renderer process to potentially perform a sandbox escape via a crafted HTML page.
(CVE-2021-4098)
Use after free in Swiftshader in Google Chrome prior to 96.0.4664.110 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. (CVE-2021-4099)
Object lifecycle issue in ANGLE in Google Chrome prior to 96.0.4664.110 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. (CVE-2021-4100)
Heap buffer overflow in Swiftshader in Google Chrome prior to 96.0.4664.110 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. (CVE-2021-4101)
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
