Linux kernel SCTP-netfilter for_each_sctp_chunk() denial of service
| linux-sctp-netfilter-dos (26194) |  Medium Risk |
Description:
Linux kernel is vulnerable to a denial of service attack, caused by an infinite loop condition that can occur in the SCTP-netfilter module for_each_sctp_chunk() function. A remote attacker could exploit this vulnerability using specially-crafted packets containing an invalid SCTP (Stream Control Transmission Protocol) chunk size to consume all available CPU resources, resulting in a denial of service.
Consequences:
Denial of Service
Remedy:
Upgrade to the latest version of Linux kernel (2.6.16.13 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 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.
