Synopsis

A web browser installed on the remote macOS or Mac OS X host is affected by an information disclosure vulnerability.

Description

The version of Apple Safari installed on the remote macOS or Mac OS X host is prior to 11.0.2, or is 11.0.2 and missing the January 8th patch.
It is, therefore, affected by a vulnerability that exists within microprocessors utilizing speculative execution and indirect branch prediction, which may allow an attacker with local user access to disclose information via a side-channel analysis.

Solution

Upgrade to Apple Safari version 11.0.2 and apply the vendor patch.
