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...

CVE-2007-3377

CVE-2007-3377 affects the Perl module Net::DNS (pre-0.60). The issue: Net::DNS generates predictable DNS query IDs (fixed increment) and can reuse the same starting ID for all child processes of a forking server, enabling remote attackers to spoof DNS responses. Connected advisories show mitigati...
