Apple has posted a security update for the Windows and OS X versions of its Safari web browser.
The company said that the Safari 5.1.4 update would address a number of vulnerabilities in the browser itself and its WebKit engine.
Among the fixes in the update is a patch which addresses dozens of memory corruption vulnerabilities in WebKit which, if exploited, could allow an attacker to remotely execute code on a targeted system.
Other WebKit fixes include a cross-site scripting vulnerability and a flaw which could potentially allow an attacker to access a user's cookie data.
Additionally, the update will address a flaw in the handling of International Domain Name (IDN) code which could leave users vulnerable to attack sites using look-alike URL characters.
The Safari update comes one day before Microsoft is due to release its monthly security update. The March Patch Tuesday release will contain fixes for vulnerabilities in Windows as well as patches for Visual Studio and Microsoft Expression.
Safari 5.1.4 will run on Windows XP SP2 systems and later and on OS X 10.6.8 and later systems.
