Subject: [Qemu-devel] [PATCH] qemu-sockets: Fix buffer overflow in inet_parse()
Date: Fri, 30 Jan 2015 20:37:55 +0100	[thread overview]
Message-ID: <1422646675-17657-1-git-send-email-kwolf@redhat.com> (raw)

The size of the stack allocated host[] array didn't account for the
terminating '\0' byte that sscanf() writes. Fix the array size.
