Mac OS X : Apple Safari < 9.1.3 WebKit Memory Corruption RCE

high Nessus Plugin ID 93593

Synopsis

A web browser installed on the remote host is affected by a remote code execution vulnerability.

Description

The version of Apple Safari installed on the remote Mac OS X host is prior to 9.1.3. It is, therefore, affected by a remote code execution vulnerability in WebKit due to a memory corruption issue. An unauthenticated, remote attacker can exploit this, by convincing a user to visit a malicious website, to cause a denial of service condition or execution of arbitrary code.

Solution

Upgrade to Apple Safari version 9.1.3 or later.
