Description Eugene Teo (Security Response) 2010-01-15 06:55:42 UTC

Description of problem:
Reported by our customer, via IT#371682.

a flaw was found in the sctp_rcv_ootb() function in the Linux kernel Stream Control Transmission Protocol (SCTP) implementation. A remote attacker could send a specially-crafted SCTP packet to a target system, resulting in a denial of service.

Acknowledgements:

Red Hat would like to thank Telesys Software for responsibly reporting this
issue.

Comment 3 Eugene Teo (Security Response) 2010-01-15 07:06:08 UTC

This issue has been rated as having important security impact by the Red Hat Security Response Team.

Before updates are applied, it is possible to reduce the risk and mitigate this flaw by blacklisting the sctp kernel module.

Red Hat Enterprise Linux 4 and 5
Add the following entries to the end of the /etc/modprobe.conf file:
install sctp /bin/true

The sctp module cannot be unloaded from a running kernel if the module is already loaded; therefore, the above changes for /etc/modprobe.conf on Red Hat Enterprise Linux 4 and 5 require a reboot to take effect.

Red Hat Enterprise MRG
Add the following entries to the end of the /etc/modprobe.conf file:
install sctp /bin/true

For customers who are unable to mitigate this should request for a hotfix via Red Hat Support until a kernel update that addresses this is available.
