Description:
Two vulnerabilities have been reported in PowerDNS Recursor, which can be exploited by malicious people to cause a DoS (Denial of Service) and potentially compromise a vulnerable system.
1) An error in length calculation when handling TCP DNS queries can be exploited to cause an overly large copy via a specially crafted packet.
Successful exploitation may allow execution of arbitrary code.
2) An error in the handling CNAME records can be exploited to crash the service.
The vulnerabilities are reported in PowerDNS Recursor versions 3.1.3 and prior. PowerDNS Authoritative Server (pdns_server) is not affected.
