DNS: PowerDNS Recursive Out of Bounds Read Denial of Service
This signature detects attempts to exploit a known vulnerability against PowerDNS. The vulnerability is due to improper processing of crafted DNS queries, leading to out-of-bounds read. A remote, unauthenticated attacker can exploit this vulnerability by sending a crafted query to the target server. A successful attack could lead to PowerDNS abnormally terminating, leading to a denial-of-service condition.
Extended Description
An issue has been found in PowerDNS Recursor before version 4.1.8 where a remote attacker sending a DNS query can trigger an out-of-bounds memory read while computing the hash of the query for a packet cache lookup, possibly leading to a crash.
