Linux SCTP fragmented control chunk denial of service
| linux-sctp-control-chunk-dos (26431) |  Low Risk |
Description:
Linux kernel SCTP (lksctp) could allow a remote attacker to cause a denial of service, caused by improper handling of fragmented COOKIE_ECHO and HEARTBEAT SCTP control chunks. A remote attacker could exploit this vulnerability to cause a kernel panic.

Remedy:
Upgrade to the latest stable version of the Linux kernel (2.6.16.16 or later), available from The Linux Kernel Archives. See References.
For Red Hat Linux:
Refer to RHSA-2006:0493-6 for patch, upgrade, or suggested workaround information. See References.
For Debian GNU/Linux:
Refer to DSA-1097-1 and DSA-1103-1 for patch, upgrade, or suggested workaround information. See References.
For SUSE Linux:
Refer to SUSE-SA:2006:028 for patch, upgrade, or suggested workaround information. See References.
For other distributions:
Apply the appropriate update for your system. See References.
Consequences:
Denial of Service
