Subject: [PATCH 1/2] netfilter: ipset: fix netiface set name overflow
Date: Thu, 22 Nov 2012 12:32:45 +0100 [thread overview]
Message-ID: <1353583966-12402-1-git-send-email-fw@strlen.de> (raw)
attribute is copied to IFNAMSIZ-size stack variable,
but IFNAMSIZ is smaller than IPSET_MAXNAMELEN.
Fortunately nfnetlink needs CAP_NET_ADMIN.
