WebKit in Apple Safari before 5.1.4 does not properly implement "From third parties and advertisers" cookie blocking, which makes it easier for remote web servers to track users via a cookie.

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 implement From third parties and advertisers     cookie blocking, which makes it easier for remote web servers to track users via a cookie. (CVE-2012-0640)

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

The remote host has Safari installed. 

Versions of Safari earlier than 5.1.4 are reportedly affected by several issues :

  - Look-alike characters in a URL could be used to masquerade a website. (CVE-2012-0584)

  - 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.
