What is CVE-2008-1146?
CVE-2008-1146 is a medium-severity vulnerability in n/a, published on 4 Mar 2008. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official 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.
Which versions are affected by CVE-2008-1146?
It affects 3 products.
Products include Cosmicperl Directory Pro, Darwin Darwin, Navision Financials Server.
