"Intel Patches Reptar Vulnerability in Intel Processors, Which Can Cause Data Theft"
Intel has patched the Reptar vulnerability Google security researchers found in its CPUs that could lead to data theft or DNS attacks. According to researchers, the Reptar flaw is a "redundant prefix" issue. When hackers execute a REP MOVSB instruction with a redundant REX prefix in an Intel processor, the chip manufacturer warns in an advisory that it can result in unpredictable system behavior. This can then cause the system to crash or hang. In some cases, it can also result in the escalation of privileges. In addition to applying the patch Intel has provided for the vulnerability, companies are advised to update their BIOS, operating system, and drivers with the latest microcode from their OEM, operating system, and hypervisor vendors. This article continues to discuss the Reptar vulnerability and Intel's response to it.
