Linux SCTP Functionality Multiple Remote DoS

high Nessus Plugin ID 21333

Synopsis

It is possible to crash the remote host by sending it a malformed SCTP packet.

Description

There is a flaw in the Linux kernel on the remote host that causes a kernel panic when it receives an SCTP packet with a chunk data packet of length 0. An attacker can leverage this flaw to crash the remote host. Additionally, other types of crafted packets can cause a remote denial of service in various SCTP related functions.

Note that successful exploitation of this issue requires that the kernel support SCTP protocol connection tracking.

Solution

Upgrade to Linux kernel 2.6.16.23 / 2.6.17.3 or later.
