Description:
A vulnerability has been reported in ISC DHCP, which can be exploited by malicious people to cause a DoS (Denial of Service) and potentially compromise a user's system.
The vulnerability is caused due to a boundary error within the "script_write_params()" function in client/dhclient.c and can be exploited to cause a stack-based buffer overflow by sending an overly long subnet-mask option.
Successful exploitation may allow execution of arbitrary code with "root" privileges, but requires that dhclient processes a specially crafted response from a malicious DHCP server.
The vulnerability is reported in DHCP 2.0 through 4.1.
