Linux SCTP ECNE Chunk Handling Remote DoS

high Nessus Plugin ID 21560
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


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


There is a flaw in the SCTP code included in Linux kernel versions 2.6.16.x that results in a kernel panic when an SCTP packet with an unexpected ECNE chunk is received in a CLOSED state. An attacker can leverage this flaw to crash the remote host with a single, possibly forged, packet.


Upgrade to Linux kernel version 2.6.17 or later.
