Mac OS X : Apple Safari < 4.0.4

high Nessus Plugin ID 42477


The remote host contains a web browser that is affected by several vulnerabilities.


The version of Apple Safari installed on the remote Mac OS X host is earlier than 4.0.4. As such, it is potentially affected by several issues :

- Multiple use-after-free issues exist in libxml2, the most serious of which could lead to a program crash.
(CVE-2009-2414, CVE-2009-2416)

- An issue in the handling of navigations initiated via the 'Open Image in New Tab', 'Open Image in New Window' or 'Open Link in New Tab' shortcut menu options could be exploited to load a local HTML file, leading to disclosure of sensitive information. (CVE-2009-2842)

- An issue involving WebKit's inclusion of custom HTTP headers specified by a requesting page in preflight requests in support of Cross-Origin Resource Sharing can facilitate cross-site request forgery attacks. (CVE-2009-2816)

- WebKit fails to issue a resource load callback to determine if a resource should be loaded when it encounters an HTML 5 Media Element pointing to an external resource, which could lead to undesired requests to remote servers. (CVE-2009-2841)


Upgrade to Apple Safari 4.0.4 or later.
