NSD packet.c Off-By-One Buffer Overflow

Medium Nessus Network Monitor Plugin ID 5040


The remote DNS server is vulnerable to a remote buffer overflow attack.


The remote host is running a version of NSD DNS Server which has a stack buffer overflow vulnerability. A remote attacker could overwrite one byte in memory, leading to a denial of service. It is possible, but unlikely, that this vulnerability could result in remote code execution.
