Description Andrej Nemec 2016-05-10 08:23:34 UTC
The print_option function in dhcp-common.c in dhcpcd through 6.9.1  misinterprets the return value of the snprintf function, which allows remote DHCP servers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted message.

Patch:
