CVE-2008-1146

UnknownEPSS 1.38%

Last modified

CVE-2008-1146 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 1.38% chance of exploitation in the next 30 days.
