CVE-2008-5162

The CVE-2008-5162 entry concerns FreeBSD kernel arc4random(9) and its entropy source during the first boot minutes. Technical details across connected docs show: affected software is FreeBSD 6.3–7.1 kernels; problem is insufficient entropy immediately after boot, delaying reseeding from Yarrow an...

PT-2008-6306 · Freebsd · Freebsd

Name of the Vulnerable Software and Affected Versions: FreeBSD versions 6.3 through 7.1 Description: The issue is related to the arc4random function in the kernel, which lacks a proper entropy source for a short time period immediately after boot. This makes it easier for attackers to predict the...

FreeBSD arc4random (9)伪随机数生成器不充分漏洞

BUGTRAQ ID: 32447 CVECAN ID: CVE-2008-5162 FreeBSD就是一种运行在Intel平台上、可以自由使用的开放源码Unix类系统。 FreeBSD内核中广泛使用arc4random9随机数生成器，一些应用依赖于该随机数生成器的加密强度。arc4random9定期用来自FreeBSD内核的Yarrow随机数生成器的熵重新提供种子，Yarrow随机数生成器从包括硬件中断等各种来源收集熵。在引导阶段，从用户域向Yarrow随机数生成器提供了额外的，以确保加密中有足够的熵。...

FreeBSD -- arc4random(9) predictable sequence vulnerability

Problem Description: When the arc4random9 random number generator is initialized, there may be inadequate entropy to meet the needs of kernel systems which rely on arc4random9; and it may take up to 5 minutes before arc4random9 is reseeded with secure entropy from the Yarrow random number...
