DHCP: ISC DHCP dhclient script_write_params Stack Buffer Overflow
This signature detects attempts to exploit a known vulnerability in the ISC DHCP dhclient script_write_params. A successful attack can lead to a buffer overflow and arbitrary remote code execution within the context of the application.
Extended Description
The ISC DHCP client 'dhclient' is prone to a remote stack-based buffer-overflow vulnerability because it fails to properly bounds-check user-supplied input before copying it into a fixed-length buffer. Successfully exploiting this issue allows a remote attacker to execute arbitrary code with superuser privileges, resulting in a complete compromise of the affected computer.
