Description:
Some vulnerabilities have been reported in the Linux Kernel, which can be exploited by malicious people to cause a DoS (Denial of Service).
1) An incorrect use of state table entries in the SCTP code when certain ECNE chunks are received in CLOSED state can be exploited to cause kernel panic via a specially crafted packet.
2) An error in the handling of incoming IP-fragmented SCTP control chunks can be exploited to cause kernel panic via fragmented COOKIE_ECHO and HEARTBEAT chunks.
3) An infinite recursion error in the "sctp_skb_pull()" function of lksctp can be exploited to crash the system during message reassembly via a specially crafted packet that contains two or more DATA fragments of a message.
4) An deadlock error within the handling of the receive buffer in SCTP can be exploited to cause a DoS via a large number of small messages sent to a receiver application that causes it to run of receive buffer space.
The vulnerabilities have been reported in version 2.6.16. Other versions may also be affected.
