Apple issued security updates today (April 15) for its Safari Web browser and iOS mobile software, tightening the screws in reaction to high-profile flaws exploited last month.
Apple updated Safari to version 5.0.5, fixing two vulnerabilities that malicious attackers could exploit in Windows and OS X to harm users’ systems, Apple explained in its press release.
At last month’s Pwn2Own hacking contest, a team from the security firm Vupen won $15,000 by successfully hacking a previous version of Safari.
Users can install Safari 5.0.5 in OS X by clicking the Apple icon and selecting Software Update.
Apple today also rolled out iOS version 4.3.2, an update to its popular mobile-operating system for the iPhone, iPad and iPod Touch, which Pwn2Own hackers also made short work of last month.
The iOS version 4.3.2 can be installed by opening iTunes, plugging the iPhone or iPad into the computer and selecting “Check for updates,” the security firm Sophos said.
Finally, Apple issued Security Update 2011-002, revoking the fraudulent security certificates that were falsely signed by the IT firm Comodo after it was hacked late last month.
