Multiple vulnerabilities in Linux SCTP 2.6.16 [MU-200605-01]
May 8, 2006


Affected Product/Versions:

Linux SCTP 2.6.16 [http://lksctp.sourceforge.net]

Product Overview:

The Linux Kernel Stream Control Transmission Protocol (lksctp) project is an
implementation of the Stream Control Transmission Protocol (SCTP) in the Linux
kernel. The primary goal of this project is to provide user applications with
a viable SCTP solution.

Vulnerability Details:

Multiple vulnerabilities exist in Linux SCTP 2.6.16 (lksctp) all resulting in
kernel panics. The crafted packets must be sent to a listening endpoint in
order to exploit these vulnerabilities.

The first vulnerablity triggered by ECNE chunks is due to the use of incorrect
state table entries for certain CHUNKS received in CLOSED state. Since this
vulnerability does not require a full 'session' to be established, the source
IP address may be spoofed resulting in a single packet triggering the panic.

The second vulnerability is triggered due to a bug in handling incoming IP
fragmented SCTP control chunks. This causes a kernel BUG in skb_pull.

Vendor Response / Solution:

All users of Linux SCTP are recommended to upgrade to 2.6.17 which fixes
these problems.

Hotfix solution to this advisory:

Patches for these two vulnerabilities are available from the following links:


Mu Security would like to thank the Linux SCTP team in advance for timely
remediation of these vulnerabilities.
