| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2008-04-02 | CVE-2008-1637 | Numeric Errors vulnerability in Powerdns Recursor 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. | 6.8 |
| 2006-11-14 | CVE-2006-4252 | Remote Denial of Service and Buffer Overflow vulnerability in PowerDNS PowerDNS Recursor 3.1.3 and earlier allows remote attackers to cause a denial of service (resource exhaustion and application crash) via a CNAME record with a zero TTL, which triggers an infinite loop. | 5.0 |
| 2006-11-14 | CVE-2006-4251 | Remote Denial of Service and Buffer Overflow vulnerability in PowerDNS Buffer overflow in PowerDNS Recursor 3.1.3 and earlier might allow remote attackers to execute arbitrary code via a malformed TCP DNS query that prevents Recursor from properly calculating the TCP DNS query length. | 7.5 |
