Description
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.
Public exploits
Exploit or proof-of-concept code for this vulnerability is publicly available, which lowers the bar for attackers. Treat it as a reason to patch sooner.
Third-party code, not reviewed by us. Public PoCs are sometimes fake or contain malware. Read the code first and run it only in an isolated lab, against systems you are authorised to test.
