Guido Vranken reported several flaws to Ubuntu's launchpad bugtracker in the dhcpcd3 package that is shipped in Ubuntu, Debian, and potentially other distributions. https://bugs.launchpad.net/ubuntu/+source/dhcpcd/+bug/1517226 Guido included a patch along with AFL-discovered inputs to trigger the issues: https://launchpadlibrarian.net/228152582/dhcp.c.patch https://bugs.launchpad.net/ubuntu/+source/dhcpcd/+bug/1517226/+attachment/4520925/+files/patch-payloads-dhcpcd.c.tar.xz Roy Marples has already addressed these issues in upstream dhcpcd packages; I believe these issues may require 2012-era CVE identifiers: http://roy.marples.name/projects/dhcpcd/finfo?name=dhcp.c&ci=27a92c6a825d6e74 I believe this represents three distinct flaws: out of bounds reads beyond the end of the supplied packet, out of bounds write before the start of the 'out' parameter, and a use-after-free. I brought this issue to the distros list on Wed, 18 Nov 2015. Thanks Download attachment "signature.asc" of type "application/pgp-signature" (474 bytes)
