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:

https://android.googlesource.com/platform/external/dhcpcd/+/73c09dd8067250734511d955d8f792b41c7213f0
