Subject: [dpdk-dev] [PATCH 5/5] examples_ip_pipeline: fix possible string overrun
Date: Mon, 31 Aug 2015 18:59:06 -0700 [thread overview]
Message-ID: <1441072746-29174-6-git-send-email-stephen@networkplumber.org> (raw)
In-Reply-To: <1441072746-29174-1-git-send-email-stephen@networkplumber.org>
If a long name was passed the code would clobber memory with
strcpy.
