Apple on Thursday issued updates for its Safari Web browser to fix more than two dozen vulnerabilities that left the browser open to Web-based attacks. The company released Safari versions 5.0.3 and 4.1.3 for Mac OS X and Windows XP SP2, Vista and Windows 7. The updated versions fix 27 reported vulnerabilities in the Safari Webkit component that made Safari users vulnerable to Web based attacks that could crash the browser or allow attackers to run their own malicious code on vulnerable systems.
