Description

<em style='font-weight:bold;'>(Description Provided by <a href="http://cve.mitre.org/cgi-bin/cvename.cgi?name=2009-2816" target="_blank">CVE</a>)</em> : The implementation of Cross-Origin Resource Sharing (CORS) in WebKit, as used in Apple Safari before 4.0.4 and Google Chrome before 3.0.195.33, includes certain custom HTTP headers in the OPTIONS request during cross-origin operations with preflight, which makes it easier for remote attackers to conduct cross-site request forgery (CSRF) attacks via a crafted web page.

Technical

This vulnerability is due to a flaw in WebKit, a third party open source browser engine. By itself, WebKit is not a functioning program for web browsing. The vulnerability is manifested when used by browsers such as Safari or Chrome. Due to the integration of WebKit with a browser, it may alter how the vulnerability manifests and could be significantly different between programs or browsers. Because of these reasons, this entry has been split out and replaces a single entry for WebKit.

Solution

Upgrade to version 3.0.195.33 or higher, as it has been reported to fix this vulnerability. An upgrade is required as there are no known workarounds.
