| | | | | Travis Goodspeed has continued finding flaws in TI microcontrollers, branching out from the MSP430 to ZigBee radio chipsets. A few days ago, he posted a flaw in the random number generator. Why is this important? Because the MSP430 and ZigBee are found in many wireless sensor systems, including most Smart Meters. Travis describes two flaws:... | |

| | | | | [AI summary] The article discusses the use of /dev/random and /dev/urandom in Linux systems for generating random numbers. It highlights that /dev/urandom is generally preferred over /dev/random due to its non-blocking nature and sufficient cryptographic security. The article also addresses misconceptions in the man pages and emphasizes that /dev/urandom is safe for most applications, including cryptographic uses, as long as the initial seeding is done properly. It mentions that while /dev/random is considered a legacy interface, it's not always necessary, and modern Linux distributions and syscalls like getrandom(2) provide better alternatives. | |

| | | Dr Silvio Cesare@silviocesare Summary In this blog post I'll discuss how to exploit the Linux kernel via a stack smashing attack. I'll be attacking the latest kernel version. I'll also introduce a vulnerable device driver that I wrote so that I can focus on the exploitation development and not the vulnerability research. A number of... | ||
