The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - WebKit in Apple Safari before 5.1.4 does not properly handle redirects in conjunction with HTTP     authentication, which might allow remote web servers to capture credentials by logging the Authorization     HTTP header. (CVE-2012-0647)

Note that Nessus relies on the presence of the package as reported by the vendor.

The version of Apple Safari installed on the remote Mac OS X host is earlier than 5.1.4.  Thus, it is potentially affected by several issues :
 
  - Web page visits may be recorded in browser history even     when private browsing is active. (CVE-2012-0585)

  - Multiple cross-site scripting issues existed in WebKit.     (CVE-2011-3881, CVE-2012-0586, CVE-2012-0587,     CVE-2012-0588, CVE-2012-0589)

  - A cross-origin issue existed in WebKit, which may allow     cookies to be disclosed across origins. (CVE-2011-3887)

  - Visiting a maliciously crafted website and dragging     content with the mouse may lead to a cross-site     scripting attack. (CVE-2012-0590)

  - Multiple memory corruption issues existed in WebKit.
