Vulnerability Title
N/A
Vulnerability Description
A certain pseudo-random number generator (PRNG) algorithm that uses XOR and 3-bit random hops (aka "Algorithm X3"), as used in OpenBSD 2.8 through 4.2, allows remote attackers to guess sensitive values such as DNS transaction IDs by observing a sequence of previously generated values. NOTE: this issue can be leveraged for attacks such as DNS cache poisoning against OpenBSD's modification of BIND.

Vulnerability Title
OpenBSD PRNG DNS Cache中毒和可预测IP ID缺陷
Vulnerability Description
当在OpenBSD 2.8至4.2的版本中使用时，一个特定的采用XOR和3-bit随机跳跃(又称运算法则X3)的伪随机数字生成器(PRNG)算法，远程攻击者通过观察一系列之前生成的值推测出一些敏感值，比如DNS处理IDs。注意：一些攻击，如DNS高速缓冲存储器阻止OpenBSD对BIND的修改，可以触发该漏洞。
