Date: Wed, 17 Jul 2013 15:46:48 -0700 From: Kamal Mostafa <kamal@...onical.com> To: linux-kernel@...r.kernel.org, stable@...r.kernel.org, kernel-team@...ts.ubuntu.com Cc: Dan Carpenter <dan.carpenter@...cle.com>, Simon Horman <horms@...ge.net.au>, Pablo Neira Ayuso <pablo@...filter.org>, Luis Henriques <luis.henriques@...onical.com> Subject: [PATCH 076/145] ipvs: info leak in __ip_vs_get_dest_entries() 3.8.13.5 -stable review patch. If anyone has any objections, please let me know. ------------------ From: Dan Carpenter <dan.carpenter@...cle.com> commit a8241c63517ec0b900695daa9003cddc41c536a1 upstream. The entry struct has a 2 byte hole after ->port and another 4 byte hole after ->stats.outpkts. You must have CAP_NET_ADMIN in your namespace to hit this information leak.
