Last modified
CVE-2009-1755 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 3.16% chance of exploitation in the next 30 days.
