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。...

CVE-2005-0106

CVE-2005-0106 affects the perl module libnet-ssleay-perl (SSLeay.pm) before 1.25. When no entropy source is set in EGD_PATH, it falls back to the file /tmp/entropy, which an attacker with write access to that file could modify to weaken cryptographic operations. Consequence: potential partial imp...
