Browser and Smartphone Exploits Fly at Pwn2Own [Recap]

With Google offering $20,000 for a Chrome sandbox exploit, Apple releasing fresh security updates, and the organisers allowing researchers to target mobile phone basebands, it was sure make for an interesting Pwn2Own contest at CanSecWest this year.

For the fifth year running, Pwn2Own invited security researchers to discover vulnerabilities and develop exploits for the most popular browsers on Mac OS X and Windows (for some reason Linux is left out this year). Traditionally IE, Firefox and Safari have gotten exploited, with Chrome being the last browser standing at last year’s competition. Google upped the ante by making it significantly more attractive to target their browser this year.

In short: Safari, Internet Explorer, iPhone and Blackberry were all successfully compromised. Chrome and Firefox survive. Hit the jump for the full details! Read moreRead more

Apple Drops iOS 4.3 and Safari 5.0.4 Security Updates Ahead of Pwn2Own Contest

In awesome day-before-just-to-try-and-screw-with-your-exploits style, Apple has released significant security patches for iOS, Safari and Apple TV. Safari, which is one of the targets at CanSecWest’s Pwn2Own contest where hackers come to demonstrate 0day exploits, has received an update to 5.0.4, and fixes over 62 bugs including major vulnerabilities in WebKit (eg. Errorjacking) and the ImageIO and libxml libraries.

iOS 4.3 patches largely the same issues in MobileSafari, as well as a remote code execution vulnerability in CoreGraphics. iOS is expected to get a lot of attention at Pwn2Own, with at least four researchers having developed exploits. Charlie Miller and Dionysus Blazakis (@dionthegod) have one exploit which doesn’t work on update, although allegedly the vulnerability hasn’t been patched yet.

Whether or not these updates thwart some of the exploits developed for Pwn2Own remains to be seen. It’ll be cool if it prevents at least one. Either way, good job to Apple for trying.

Update: Just found out that target iPhones at Pwn2Own won’t be running the latest iOS 4.3 which does indeed prevent a number of exploits. Here’s a recap of the Pwn2Own action.

Lastly, Apple TV has been updated to 4.2 to patch a couple not-so-critical vulnerabilities in libfreetype and libtiff that could allow code execution if a malicious image were opened.

Hi the jump for the long list of issues fixed in iOS 4.3. Read moreRead more

Understanding Apple’s Approach to Security

With Apple’s growing market share in desktop computers, and relative dominance in mobile computing, the security of Mac OS X and iOS are increasingly becoming talking points. Apple continues to tout the security of OSX, whilst the iOS hacker community keeps looking for (and finding) exploits that will allow them to jailbreak iPhones and iPads. This article is my own look into Apple’s history and strategy, and how this translates into the company’s focus on security today. Read moreRead more
