Linux kernel netfilter xt_sctp denial of service
| linux-xt-sctp-dos (27384) |  Low Risk |
Description:
Linux kernel is vulnerable to a denial of service attack, caused by an infinite loop condition that can occur in the netfilter/xt_sctp.c file. A remote attacker could exploit this vulnerability using specially-crafted packets containing a SCTP (Stream Control Transmission Protocol) chunk size of zero 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 (2.6.17.1 or later), available from The Linux Kernel Archives Web site. See References.
For SUSE Linux:
Refer to SUSE-SA:2006:047 for patch, upgrade, or suggested workaround information. See References.
