Subject: [libnftnl PATCH 3/7] expr/ct: prevent array index overrun in ctkey2str()
Date: Fri, 12 Aug 2016 01:33:35 +0200 [thread overview]
Message-ID: <1470958419-32602-4-git-send-email-phil@nwl.cc> (raw)
In-Reply-To: <1470958419-32602-1-git-send-email-phil@nwl.cc>
The array has NFT_CT_MAX fields, so indices must be less than that
number.
Fixes: 977b7a1dbe1bd ("ct: xml: use key names instead of numbers")
