CVE-2010-3432: Input Validation

First published: Mon Sep 27 2010(Updated: )

Description of problem: sctp_packet_config() is called when getting the packet ready for appending of chunks. The function should not touch the current state, since it's possible to ping-pong between two transports when sending, and that can result packet corruption followed by skb overlfow crash. Upstream commit: <a href="http://git.kernel.org/linus/4bdab43323b459900578b200a4b8cf9713ac8fab">http://git.kernel.org/linus/4bdab43323b459900578b200a4b8cf9713ac8fab</a> Reference: <a href="http://marc.info/?l=linux-netdev&amp;m=128453869227715&amp;w=3">http://marc.info/?l=linux-netdev&amp;m=128453869227715&amp;w=3</a> <a href="http://www.spinics.net/lists/linux-sctp/msg01051.html">http://www.spinics.net/lists/linux-sctp/msg01051.html</a> Essentially, we are resetting the contents of the packet when it's not empty.
