Intel patches critical security bug in vPro processors
Intel has released a patch for its series of silicon-based security protections after researchers from Poland identified flaws that allowed them to completely bypass the extensions.
The implementation errors in Intel's TXT, or trusted execution technology, mean the feature can't be counted on as advertised to protect sensitive files and prevent systems from booting operating systems that have been tampered with. The vulnerability affects the Q35, GM45, PM45 Express, Q45, and Q43 Express chipsets.
"We again showed that an attacker can compromise the integrity of a software loaded via an Intel TXT-based loader in a generic way, fully circumventing any protection TXT is supposed to provide," researchers with the Invisible Things Lab stated in a press release (PDF) issued Monday.
