This anomaly triggers if it detects that the character in a DHCP Host Name is out of the valid range. This can indicate that your system is under attack.
ISC DHCPD is prone to a remotely exploitable buffer overflow vulnerability. This issue exists in routines responsible for logging hostname options provided by DHCP clients. Successful exploitation could result in execution of arbitrary code in the context of the DHCPD server. This issue is reported to affect ISC DHCPD versions 3.0.1rc12 and 3.0.1rc13. The vulnerable code exists in previous versions of ISC DHCPD 3, but is only believed to be exploitable in these two releases.
