Description

The version of Google Chrome installed on the remote macOS or Mac OS X host is prior to 54.0.2840.87. It is, therefore, affected by a remote code execution vulnerability in the V8 component due to an out-of-bounds access error that occurs when handling stable map assumptions for globals. An unauthenticated, remote attacker can exploit this, via a specially crafted website, to cause a denial of service condition or the execution of arbitrary code.

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