How Assumptions May Be Making Us All Less Secure

In the space of a given year, untold thousands of vulnerabilities are found in operating systems, applications and plug-ins. In many cases, the affected vendors fix the flaws, either with a patch, a workaround or some other mitigation. But there’s also a huge population of security bugs that...

Decades On, Buffer Overflows Still the Target

Buffer overflows have been a serious security problem for software developers for several decades now, but the history of exploitation research on this class of flaws is relatively short. Attackers and researchers originally focused on finding, fixing or exploiting buffer overflows on non-x86...

Mozilla Falls Short on Firefox ASLR Implementation

Like Apple’s Safari, the open-source Mozilla Firefox browser does not properly implement ASLR, a key anti-exploit mitigation that can limit the damage from hacker attacks. Nils, the U.K.-based researcher who compromised a Windows machine running Firefox for the second year in a row told me it’s...

Apple Safari Still Easiest to Hack

For the third year in a row, security researcher Charlie Miller successfully compromised a fully patched MacBook Pro machine with a Safari vulnerability and exploit. Despite Apple’s best efforts at making it difficult to exploit the Mac OS X, Miller’s exploits show that Safari is still easy...

Despite Hack, IE 8 Most Protected Browser

Despite the survival of Google Chrome and the fall of Internet Explorer 8 running on Windows 7, all the browser hackers at the contest maintained that Microsoft’s browser is by far the most difficult to exploit. For starters, IE 8 is the only browser to fully — and properly — implement ASLR see...

ASLR + DEP Bypass Puts Hackers Ahead

When Microsoft shipped Windows Vista, the addition of security technologies like ASLR Address Space Layout Randomization alongside DEP Data Execution Prevention and SafeSEH were held up as major roadblocks to hacker attacks. With every new service pack of OS upgrade, these mitigations got stronge...
