ISC BIND inet_network buffer overflow

iscbind-inetnetwork-bo (39670) The risk level is classified as HighHigh Risk

Description:

ISC BIND is vulnerable to an off-by-one buffer overflow, caused by improper bounds checking by the inet_network() function. By sending a specially-crafted argument, a remote attacker could overflow a buffer and execute arbitrary code or cause the system to crash.
