Dnrd » Dnrd » 1.3 : Security Vulnerabilities, CVEs,

Buffer overflow in Domain Name Relay Daemon (DNRD) before 2.19.1 allows remote attackers to execute arbitrary code via a large number of large DNS packets with the Z and QR flags cleared.

The DNS implementation of DNRD before 2.10 allows remote attackers to cause a denial of service via a compressed DNS packet with a label length byte with an incorrect offset, which could trigger an infinite loop.

Multiple implementations of the DNS protocol, including (1) Poslib 1.0.2-1 and earlier as used by Posadis, (2) Axis Network products before firmware 3.13, and (3) Men & Mice Suite 2.2x before 2.2.3 and 3.5.x before 3.5.2, allow remote attackers to cause a denial of service (CPU and network bandwidth consumption) by triggering a communications loop via (a) DNS query packets with localhost as a spoofed source address, or (b) a response packet that triggers a response packet.

Domain Name Relay Daemon (dnrd) 2.10 and earlier allows remote malicious DNS sites to cause a denial of service and possibly execute arbitrary code via a long or malformed DNS reply, which is not handled properly by parse_query, get_objectname, and possibly other functions.
