Linux Kernel Netfilter *_conntrack_proto_sctp.c sctp_new Function Unknown Chunk Type Remote DoS

medium Nessus Plugin ID 25483
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.

Synopsis

It is possible to crash the remote host by sending it a specially- crafted packet.

Description

There is a flaw in the SCTP code included in Linux kernel versions before 2.6.21.4 that results in a kernel panic when an SCTP packet with an unknown chunk type is received. An attacker can leverage this flaw to crash the remote host with a single, possibly forged, packet.

Solution

Upgrade to Linux kernel version 2.6.21.4 or later.
