Summary

Off-by-one error in the packet_read_query_section function in packet.c in nsd 3.2.1, and process_query_section in query.c in nsd 2.3.7, allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via unspecified vectors that trigger a buffer overflow.

    descriptionNLnet Labs : A one-byte buffer overflow has been reported in NSD. The problem affects all versions 2.0.0 to 3.2.1. The bug allows a carefully crafted exploit to bring down your DNS server. It is highly unlikely that this one byte overflow can lead to other (system) exploits.
