Discussion

ISC DHCP 'dhclient' 'script_write_params()' Stack Buffer Overflow Vulnerability

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.

Exploit / POC

ISC DHCP 'dhclient' 'script_write_params()' Stack Buffer Overflow Vulnerability

A working commercial exploit is available through VUPEN Security - Exploit and PoCs Service. This exploit is not otherwise publicly available or known to be circulating in the wild.
