FreeBSD Kernel Critical Update: arc4random predictable sequence vulnerability

Posted on in Categories FreeBSD, Security, Security Alert last updated November 25, 2008

FreeBSD today released a core (kernel) patched to plug “arc4random predictable sequence vulnerability” security hole in its operating systems version 6.x and 7.x stable release. When the arc4random random number generator is initialized, there may be inadequate entropy to meet the needs of kernel systems which rely on arc4random; and it may take up to 5 minutes before arc4random is reseeded with secure entropy from the Yarrow random number generator. All security-related kernel subsystems that rely on a quality random number generator are subject to a wide range of possible attacks. This update has been rated as having important security impact.

Excellent article – you can find information about GCC extensions for the C language. The Linux kernel uses several special capabilities of the GNU Compiler Collection (GCC) suite. These capabilities range from giving you shortcuts and simplifications to providing the compiler with hints for optimization.

This article provides a glimpse of the techniques made available by GCC in the Linux kernel. You can read more about all the available extensions for both C and C++ in the GNU GCC manual.
