The supersede_lease function in memory.c in ISC DHCP (dhcpd) server 2.0pl5 allows remote attackers to cause a denial of service (application crash) via a DHCPDISCOVER packet with a 32 byte client-identifier, which causes the packet to be interpreted as a corrupt uid and causes the server to exit with "corrupt lease uid."Show less

The default configuration of ISC BIND before 9.4.1-P1, when configured as a caching name server, allows recursive queries and provides additional delegation information to arbitrary IP addresses, which allows remote attackers to cause a denial of service (traffic amplification) via DNS queries with spoofed source IP addresses.Show less

An "incorrect assumption" in the authvalidated validator function in BIND 9.3.0, when DNSSEC is enabled, allows remote attackers to cause a denial of service (named server exit) via crafted DNS packets that cause an internal consistency test (self-check) to fail.Show less

Buffer overflow in the code for recursion and glue fetching in BIND 8.4.4 and 8.4.5 allows remote attackers to cause a denial of service (crash) via queries that trigger the overflow in the q_usedns array that tracks nameservers and addresses.Show less

The DHCP daemon (DHCPD) for ISC DHCP 3.0.1rc12 and 3.0.1rc13, when compiled in environments that do not provide the vsnprintf function, uses C include files that define vsnprintf to use the less safe vsprintf function, which can lead to buffer overflow vulnerabilities that enable a denial of service (server crash) and possibly execute arbitrary code.Show less

Buffer overflow in the logging capability for the DHCP daemon (DHCPD) for ISC DHCP 3.0.1rc12 and 3.0.1rc13 allows remote attackers to cause a denial of service (server crash) and possibly execute arbitrary code via multiple hostname options in (1) DISCOVER, (2) OFFER, (3) REQUEST, (4) ACK, or (5) NAK messages, which can generate a long string when writing to a log file.Show less

ISC dhcrelay (dhcp-relay) 3.0rc9 and earlier, and possibly other versions, allows remote attackers to cause a denial of service (packet storm) via a certain BOOTP packet that is forwarded to a broadcast MAC address, causing an infinite loop that is not restricted by a hop count.Show less

Multiple stack-based buffer overflows in the error handling routines of the minires library, as used in the NSUPDATE capability for ISC DHCPD 3.0 through 3.0.1RC10, allow remote attackers to execute arbitrary code via a DHCP message containing a long hostname.Show less

The DNS resolver in unspecified versions of Infoblox DNS One, when resolving recursive DNS queries for arbitrary hosts, allows remote attackers to conduct DNS cache poisoning via a birthday attack that uses a large number of open queries for the same resource record (RR) combined with spoofed responses, which increases the possibility of successfully spoofing a response in a way that is more efficient than brute force methods.Show less

The DNS resolver in unspecified versions of Fujitsu UXP/V, when resolving recursive DNS queries for arbitrary hosts, allows remote attackers to conduct DNS cache poisoning via a birthday attack that uses a large number of open queries for the same resource record (RR) combined with spoofed responses, which increases the possibility of successfully spoofing a response in a way that is more efficient than brute force methods.Show less

BIND 4 and BIND 8, when resolving recursive DNS queries for arbitrary hosts, allows remote attackers to conduct DNS cache poisoning via a birthday attack that uses a large number of open queries for the same resource record (RR) combined with spoofed responses, which increases the possibility of successfully spoofing a response in a way that is more efficient than brute force methods.Show less

BIND 8.3.x through 8.3.3 allows remote attackers to cause a denial of service (termination due to assertion failure) via a request for a subdomain that does not exist, with an OPT resource record with a large UDP payload size.Show less
