Critical Flaw Found in Intel Chip

Researchers have discovered a vulnerability that would allow hackers to install malware.

Infosecurity Magazine Explains:

Researchers are claiming to have found a way to bypass a widely used defence against attempts to install malware by exploiting operating system or application vulnerabilities.

Address space layout randomization (ASLR) works to defend against a range of attacks by randomizing the locations of code in computer memory.

Now, in their paperJump Over ASLR: Attacking Branch Predictors to Bypass ASLR, researchers at the State University of New York and University of California describe a newly discovered flaw in Intel chips which allows them to bypass ASLR.

The researchers were able to launch a so-called 'side channel' attack on a Haswell chip’s branch target buffer (BTB), which resides in the branch predictor part of the CPU.
