The remote Debian 11 host has packages installed that are affected by a vulnerability as referenced in the dsa-5110 advisory.

  • Type confusion in V8 in Google Chrome prior to 99.0.4844.84 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. (CVE-2022-1096)

Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
