FKIE_CVE-2008-1637

Vulnerability from fkie_nvd - Published: 2008-04-02 17:44 - Updated: 2026-06-16 22:52
Severity
Summary
PowerDNS Recursor before 3.1.5 uses insufficient randomness to calculate (1) TRXID values and (2) UDP source port numbers, which makes it easier for remote attackers to poison a DNS cache, related to (a) algorithmic deficiencies in rand and random functions in external libraries, (b) use of a 32-bit seed value, and (c) choice of the time of day as the sole seeding information.
