Mac OS X Top Target in Browser Beatdown
Both the Firefox and Safari vulnerabilities that he proved were exploited on a Mac OS X system. The German hacker said the latest versions of both Firefox and IE take full advantage of features built in to Windows Vista that make it far more difficult to reliably exploit than on the current version of OS X. Those features, including “data execution prevention” (DEP) and “address space layout randomization,” (ASLR) don’t appear to be properly implemented between OS X and versions of Safari and Firefox built for that operating system, Nils said.
“It’s quite easy to write an exploit for Firefox on OS X compared to Firefox on Vista,” he said.
